Liquid Level Indicator, Float Switch & Sensors

Float Operated Liquid Level Indicator Information

Float-Operated, Gauge board style, Liquid Level Indicators

Float-operated, Liquid Level Indicators and Water Level Indicators show the level of the water or other liquid in storage tanks, with an accuracy of ±1". Linear measurement can be supplied to customer's specifications; optional designs are available for all types of storage tanks and special requirements. (Also available in metric measurements.) All interior components are stainless steel. Gauge boards are available in galvanized, aluminum, or stainless steel. 90º elbows are made from A-356 aluminum with stainless steel trim and high temperature pulleys which are made with ULTEM and can withstand temperatures of 400º+. This is a complete water level and liquid level package including all necessary piping for installation.
The Tube style level indicator
The TUBE style full travel liquid level indicator is based on the same principals at the standard board style level indicator; however we redesigned and updated the conventional level board and marker to a 3.5" polycarbonate tube with an internal marker or indicator. This TUBE does not contain fluid, but rather uses an internal float switch inside the tank, cabled to the neon orange indicator needle. The TUBE is also available with a vapor tight accessory to prevent H2S gas from escaping into the atmosphere.

Some benefits of this TUBE style Liquid Level Indicator are:
  • Reduced service calls because the cable for the float switch and indicator are protected from the wind by being sealed within the TUBE. Minimizes alignment issues because the TUBE is coupled together. The round design of the TUBE is resistant to flex, pull, and chatter created in high winds.
  • Fast installation, because no hardware is required to fix the TUBE to the TUBE brackets. Bracket and board alignment are no longer an issue because the brackets can be applied anywhere down the length of the TUBE. Sections are designed to couple together quickly, similar to PVC pipe. Very light, at only 3lbs. per 8' section. (Dramatically reduces freight costs as well.)
  • Nearly indestructible and will not crack or misshape, even under severe impact. Rated to 280 degrees F. Poly blended with Tinuvin 1577 UV protectant to resist weatherization.
The material used for the TUBE is the same material commonly used for headlight covers on automobiles, skylights, and even cockpit canopies in fighter jets.
Level Indicator Markers

Water Level & Liquid Level Indicator Information

A weather-resistant vinyl scale, with black numerals and intermediate marks on a white background, is mounted on a steel backing. Direct reading scale in 1", 6" and 1' intervals, allows the liquid or water level to be read quickly from a considerable distance. Optional 2:1 compressed scale keeps the level indicator above the reach of vandals. This is also known as a "1/2 travel" indicator.
