The main element of the glass level gauge is the gauge body. Incorporated into this level gauge body are the liquid channel (if necessary the heating channel) and the seating faces for the chambered seals and sight glasses.

Onto the level gauge body are mounted, or are already integrated, the valve heads and process connections. Drain or vent are also possible.

The glasses and/or mica shields as well as the seals are fitted, secured and sealed with the aid of U-bolts and covers or pressure frames. Glasses from borosilicate glass in accordance with DIN 7081 are used.

For steam, the glasses can be used up to 243 °C, with mica design to 300 °C. For other media, temperatures up to 300 °C are possible, in special cases up to 374 °C. The use of mica is needed for specific applications.

Local level gauge is an important measurement for many process control applications. It provides a reliable way to confirm the level gauge height. It allows a way to check and calibrate level transmitters. It can be used to temporarily and manually control the liquid level gauge when the normal control systems are down. And it offers a redundant technology to measure level gauge.

Two technologies typically used for local indication are armored sight glass and magnetic level gauge.

Armored sight glass usually consists of two armored castings that sandwich a piece of glass, allowing direct visibility of the liquid level gauge. A magnetic level gauge is typically made up of a float containing a magnet that follows the liquid level gauge inside of a chamber. The position of the float inside the chamber is indicated outside by dual-colored flappers embedded with magnets. As the magnet inside the float interacts with the magnets on the flapper outside of the chamber, the flapper turns and changes color to indicate level gauge.

When deciding which technology to use, it is important to look at the long-term cost of ownership rather than just the upfront cost of the unit. Sight glass technology typically has a lower upfront cost than an MLI; however, an MLI has many benefits during installation and normal operations that result in a lower total cost of ownership in the long run.

The four key ways — enhanced safety, maintenance, increased visibility and simplified installation — in which an MLI will actually reduce overall cost over time and improve functionality are discussed in this article. We will also go through an example of comparing the total cost of ownership of a sight glass to that of an MLI over a five-year period. A lot of these values are estimates and will vary greatly on changing applications and from plant to plant. In this example, we will use a 3’ indication length and assume our initial upfront cost of the sight glass is $450 while our MLI has a starting cost of $2,200.

Visual level indicators and tank level gauges are ideal for continuous indication of liquid level in storage tanks and vessels where visual indication at the tank is required.

Level gauge represent the trusted, durable, more versatile and safer alternative to sight glasses and feature stainless steel, alloy or engineered plastic housings.

Visual level gauge mount externally to the top or sides of tanks and provide easy-to-read continuous level gauging (the LED SureSite can even provide continuous level indication dark environments).

We specialize in the development and engineering magnetic level indicators, liquid level gauges and valve product lines. We also manufacture, steam level indicators, and liquid level gauge accessories.

Steam-Trac

Our extensive Steam-Trac product line was designed specifically for several models of water level/steam level gauges with pressure from 300 PSI working steam pressure to 3000 PSI working steam pressure.

Glass-Trac

Glass-Trac Gauges, formally Daniel Level Gauge & Valve, are available in three main types: Reflex, Transparent, & Tubular. These direct reading instruments are available in many different materials to meet your specific process conditions.

Steam Valves

Steam valves are designed specifically for use with water level gauges in steam/water service. The angled flow path compactly eases installation of the level gauge, bringing the assembly connection point to the side. Each model is designed to prevent steam galling and maximize packing life to extend the longevity of the valve.

The maximum level guge is a cost-effective measuring device that indicates the maximum water level gauge by tidal waves or other level fluctuations over a color marking. It is based on the simple principle of color marking. The threshold level gauge is used for preservation of evidence and provides accurate data for later post-processing of flood events.

Rugged cylinders made of Plexiglas and a fiberglass reinforced plastic measuring rod with easy to read E-scale in cm graduation.

Self-adhesive, transparent ribbon to display the highest water level gauge. To change the ribbon, you need to solve only one single screw.

Simple operation: water thaz rises in the cylinder, completely washes out the color to the respective water level gauge.

Clear result: A sharp dividing line between colored and colorless area enables accurate reading of the maximum water level gauge.

Unaffected by waves and debris: The straining device acts as filter for coarse dirt and acts as a damping device preventing influence by wash of waves in the measuring cylinder.
