The bypass level gauge is one of the simplest and most robust method to liquid level monitoring.

Bypass level gauges are one of the simplest and most robust means of liquid level monitoring. A chamber is mounted on the side of a tank or container by two process connections. This direct connection ensures that the level in the chamber corresponds precisely to the level of the liquid in the tank or container.

Inside the bypass chamber there is a cylindrical float with built-in permanent magnets, where the concentrated magnetic field produced travels through the chamber wall to an external indicator. Along with the magnetic roller indicator, the Bypass Level Gauges can also be equipped with magnetic switches and level transmitters (magnetostrictive or reed type).

Advantages are a simple, robust, and rugged design, no direct contact with aggressive fluids by sensitive measurement and indicating instruments, and guaranteed operation of the magnetic roller indicator without requiring an auxiliary power source, even in the event of power failures. These gauges are applicable throughout industry thanks to the use of a range of corrosion-proof materials. Designs are available for pressure ranges from vacuum up to 400 bar, temperature ranges from 167°C to +400°C, and densities of 350 kg/m³.

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.

A level gauge monitors the liquid level of the chemical you’re storing in your polyethylene tank. There are several types of gauges, including clear tube level gauges and ultrasonic level gauges. While we can provide a variety of level indicators, we almost always recommend our reverse float gauge.

What Is a Reverse Float Level Gauge?

A reverse float level gauge makes it easy to know how much chemical is in your tank, from outside the tank wall.

The reverse float gauge can be counterintuitive at first, but it’s an elegant and simple solution that gives you a clear reading from outside of the tank. The level system contains a float inside the tank, which is connected by a rope to a weighted level indicator. The indicator is housed in a vertical tube along the exterior sidewall of the tank.

As the tank is filled, the chemical lifts the float, and the pulley system moves the weighted indicator downward. As the tank empties, the float inside the tank lowers, pulling the indicator on the outside upwards.

In essence, you’re looking at an upside-down representation of the chemical’s level in the tank. When the tank is full, the visual indicator is at the bottom of the tube, and when the tank is empty it’s at the top. It is a reverse indication of the level in the chemical tank—thus, a reverse float 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.

The magnetic level gauge is now widely used throughout process industries as an effective level control device.

A magnetic level gauge is often used in applications where a sight glass (or glass sight gauge) is either ill-suited based on process variables or is underperforming based on plant requirements. These can include enhanced safety for personnel; environmentally risky situations including media leakage or fugitive emissions; need for maintenance reduction; or need for high visibility from a distance.

Safety

The obvious safety benefit of the level gauge over a sight glass is reduced chance of breakage. If the process fluid is under extreme pressure or temperature, the likelihood of sight glass breakage is increased. The pressure boundary of an level gauge is made of robust metal, frequently the same as the vessel piping, making level gauge as safe as the surrounding piping system itself. The indicators, transmitters, and switches are all mounted externally and, therefore, are unaffected by toxicity, corrosiveness, or other process fluid characteristics.

Another safety benefit is that the chemical compatibility with the fluid in an level gauge is restricted to only three components, the metallic chamber, gaskets and float. With glass sight gauges, the process fluid may have chemical compatibility issues with any of the wetted materials—glass, metal, or sealants.

Maintenance

Level gauges are virtually maintenance free once installed because the indicator never touches the process fluid. With sight glasses, the gauges must be periodically checked for leaks and cleaned on a regular basis. Scaling, etching and build-up on the glass from the process fluid can cause the sight glass to become unreadable.

Visibility

Visibility of the fluid level from long distances is another major reason for selecting an level gauge over a sight glass gauge. Sight gauge level indicators are intended to be viewed at maximum distances of around 10 feet (3 meters). However, the bright contrasting colors of the flags or a fluorescent shuttle on an level gauge permit visible level indication at distances up to 100 feet (30 meters) or greater.

Magnetic float level gauges, also known simply as magnetic level gauges or magnetic level indicators, provide a continuous visual indication of liquid level in a vessel or tank. Being a robust, relatively cheap level measurement technique suitable for high pressure systems they are found throughout the process, oil & gas, refinery, chemical, petrochemical, and power generation industries.

How does a Magnetic Level Gauge Work?

A magnetic level gauge contains a float, typically made from stainless steel, titanium or plastic which contains an integral, permanent omni-directional magnet. The float is contained in a bypass chamber connected to the vessel. This buoyant float rises and falls with the liquid or interface level whilst the magnet “flips” the magnetic wafers mounted externally to the chamber. As the float rises and falls each wafer rotates 180° and so presents a contrasting colour.

General industry practice is that the wafers above the float show white, whilst those below show red. Hence the indicator then presents a clearly defined and accurate level measurement of the liquid in the chamber.

Float Magnet Construction

The magnetic field is the heart of the magnetic level gauge – the stronger the field, the more reliable the instrument will function. Some manufacturers use a single annular ring magnet, others use a series of single bar magnets in a circular array in their float design. These designs tend to provide better performance than a single bar magnet.

Mounting of Magnetic Level Gauges

Like Reflex Gauges, magnetic level gauges are connected laterally to a vessel via at least 2 process connections. The process connections can be flanged, threaded or welded. The level in the bypass chamber corresponds to the level in the vessel. It is worth noting that the bypass chamber can be manufactured to any length and mounted to suit the best viewing angle therefore bespoke level gauges can be made to suit awkward installations. It is common practice to provide shut off valves between vessel and level gauge to allow removal of the level gauge without emptying the vessel. Depending on the properties of the fluid being measured, and process conditions a vent valve and/or a drain valve may also be specified in the hookup. The highly contrasting colours used on the level gauge flappers means there is normally no need to provide an additional light as is often the case with reflex level gauges.

Float Damage Warning

Many magnetic level gauge manufacturers offer the option of incorporating a damaged float warning system. This is achieved by extending the bypass chamber below the bottom process connection enough to allow the float to pass the process connection. The indicator wafers below the process connection are mounted either with their colours in reverse, or coloured yellow and white. Should the float drop into that zone the wafers will turn presenting a sharp, immediately readable indication of float failure.

Interface Applications

The magnetic level gauge is ideally suited for measuring a liquid interface. Floats are available to meet a variety of specific gravities to suit the liquids being monitored – many manufacturers offer floats suitable for specific gravity ranges of 0.33-2.2. See our page on Liquid Level Interface Measurement for mor information on measuring liquid interface.
