Water tank level gauges are used to quickly tell how much water is in your storage tank at any given time. We sells two types of level gauges: electronic indicators and mechanical indicators.

Electronic Indicators

Water tank level gauges with electronic indicators are a convenient way to keep an eye on your water levels from inside your own home or office.

Electronic level gauges consist of a transmitter and a receiver. The electronic indicator inside the tank transmits a wireless signal to a receiver located in the home or office.

Level gauges with electronic indicators eliminate the need for you to go to the actual physical location of the tank to read the water level.

Mechanical Indicators

Water tank level gauges with mechanical indicators work by using a weighted float and an indicator. The indicator is connected to a counter-weight which moves down with the rising water level and lifts up the float.

Level gauges with mechanical indicators are precisely accurate, as the sliding indicator located on the outside of the tank is able to match with the water level exactly.

Unlike level gauges with electronic indicators, those with mechanical indicators will never go down on you. Since there are no electronic parts,no power source is required and certainly no batteries. That makes these gauges an appealing option over those with electronic indicators.

Of course, the best one is whichever most closely suits the needs of your rainwater harvesting system.

Armoured level gauge: Armored level gages are used in a variety of applications, such as in petrochemical refineries and chemical plants. They work well in high-pressure environments, coming in a variety of PSI ratings up to 4000 PSI. They are available with transparent and reflex gauge glasses.

Tubular level gauge: Tubular gauges come with a clear or red line Borosilicate (Pyrex) to help improve visibility and measurement of clear fluids. They are often used in low-pressure applications up to 600 psi. Normally, they are recommended for use with oils and petrochemical liquids as opposed to water or steam as there is a possibility of the level gauge’s steel valves developing rust or corrosion. However, the tubular gauges sold at McRae Engineering have automatic valves made with corrosion-resistant ball checks and stainless steel valves.

Magnetic type level gauge: For this type of level gauge, the chamber is constructed of non‐magnetic materials, with its float engineered and located inside the chamber. It is sized and weighed to the specific gravity of the process fluid to be measured. The float contains a 360° magnetic assembly, generating a strong uniform magnetic circuit. The float will move according to the changes in the liquid level, allowing for precise measurements.

Liquid level gauges are industrial meters that are used to determine the level of a liquid in a process tank. Liquid level gauge calibration is used to ensure proper readings are obtained when using level gauges.

They have several advantages including durability for severe environments and also having the ability to withstand high temperatures and pressure. They are easy to read from a distance and can be used in addition to a switch or alarm in a system. There is little maintenance required and all repairs can be done without disturbing the system.

They can also be customized for extreme applications. Our liquid level gauge & valve specialists are available to answer your product specification questions.

The level gauge model BNA consists of a bypass chamber, which, as a communicating tube, is connected laterally to a vessel via at least 2 process connections (flanged, threaded or welded). Through this type of arrangement of the level gauge, the level in the bypass chamber corresponds to the level in the vessel. The float with a built-in permanent magnetic system, which is mounted within the bypass chamber, transmits the liquid level, contact-free, to the magnetic display mounted to the outside of the bypass chamber. In this are fitted, at 10 mm intervals, two-coloured plastic rollers or stainless steel flaps with bar magnets.

Through the magnetic field of the permanent magnetic system in the float of the level gauge, the display elements, through the wall of the bypass chamber, are turned through 180°. For an increasing level from white to red; for a falling level from red to white.

Thus the level gauge clearly displays the level of a vessel without power supply.

Transparent level indicators are highly useful in chemical industries and petrochemical fertilizers. As the fluid is stored in high pressure and high temperature, the transparent level gauge is very useful to find the fluid level.

Working principle of the transparent level gauge

Apart from glass tube level gauges, transparent level gauges are always fitted with two plate transparent glasses between which the fluid is contained. The fluid level is indicated as the result of the different transparency of the two media and in some cases (for water steam), by conveying upwards on to the surface of separation (between liquid and gaseous substances) a source of light located at the back of the gauge, the rays of which are totally reflected down to the observer.

Applications

Transparent level gauges are suitable for almost all installations.

In fact they permit:

• the use of mica shields or Polytrifluorochloroethylene shields to protect the glass from the corrosive action of the process fluid.
• the observation of interface.
• the observation of the liquid colour.

This instrument consists of a metal body, machined to have an internal chamber and one or more front windows (on each side of the gauge). On each window a special high resistance plate transparent glass is applied with sealing joint and metal cover plate hold by bolts and nuts.

The chamber of the transparent level gauge is connected to vessel with cross fittings and flanged, threaded or welded ends. Usually, between the instrument and its connecting ends, valves are fitted to consent shut-off piping and to disassemble the level gauge without to empty the vessel. Drain valves can also be fitted to cross fittings device.

To avoid leakage in case of glass breakage, safety ball-check device can be provided in cross-fittings or shut-off valves in the transparent level gauge. This kind of indicator is suitable for water/steam. To protect glass surfaces from corrosive action of the process fluid, Transparent Level Gauges can be fitted with Mica shields or Polytrifluorochloroethilene shields. This kind of indicator is suitable for liquids colorless and very fluid.

Level Gauge

In some case (i.e. for water/steam) the best reading is obtained by conveying upwards on the surface of separation (liquid/steam or vapor interface), a source of light, located on the back of the gauge, the rays of which are totally reflected down to the observer.

Based on the principle of magnetic coupling and buoyancy, the magnetic level gauge provides real-time measurement for level and interface.

Magnetic level gauge is connected to a process vessel. Within the chamber is a float containing a 360° magnetic ring. Outside of the chamber is an indicator equipped with a vacuum glass tube, which contains a bicoloured two-face magnetic bargraph.

In response to the level movement, the float moves accordingly, forcing the magnetic bargraph to turn and change color. True liquid level is indicated or “read” from the corresponding point on the measuring scale.

The level gauge, or sightglass is to liquid level measurement as manometers are to pressure measurement: a very simple and effective technology for direct visual indication of process level. In its simplest form, a level gauge is nothing more than a clear tube through which process liquid may be seen.

A level gauge is not unlike a U-tube manometer, with equal pressures applied to both liquid columns (one column being the liquid in the gauge sightglass, the other column being the liquid in the vessel).

Level gauge valves exist to allow replacement of the glass tube without emptying or depressurizing the process vessel. These valves are usually equipped with flow-limiting devices in the event of a tube rupture, so too much process fluid does not escape even when the valves are fully open.

Some level gauges called reflex gauges are equipped with special optics to facilitate the viewing of clear liquids, which is problematic for simple glass-tube sightglasses.

A weakness of glass-tube level gauges is the glass tube itself. The tube must be kept in a clean condition in order for the liquid level to be clearly visible, which may be a problem in a dirty-liquid service. Also, glass tubes may rupture if subjected to thermal or mechanical shock. One solution to this problem is to eliminate the glass tube entirely, replacing it with a non-magnetic metal tube (e.g. stainless steel) containing a magnetized float, with magnet-sensing indicator flags outside of this tube to visually indicate level.

An Inside Look at the Reverse Float Level Gauge

Knowing the liquid level in a chemical storage tank is important for a number of reasons. You have to know when to order more chemical, and certain chemicals have to be stored at a specific level to maintain their properties and/or operational requirements. A reverse float level gauge is helpful in that it lets you know, from the outside of the system, how much chemical is in your tank.

Why Design a Level Gauge

A level gauge of any kind monitors the liquid level of what is being stored in the polyethylene tank. There are several types of gauges including clear tube level gauges, ultrasonic level gauges, etc. While it works with many types of level indication, in almost all cases we recommend our reverse float gauge for use with chemical storage tanks.

How a Reverse Float Level Gauge Works

Perhaps counterintuitive at first glance, this simple level system contains a float inside the tank and a visual indicator on the outside. As the tank is filled, the chemical lifts the float which in turn allows the weighted indicator on the outside to move down. This is done using a pulley system with polypropylene rope and PVC rollers inside of PVC elbows. As the tank empties, the float inside the tank drops pulling the indicator up. This is why it is called a reverse float level gauge.
