Downhole submersible liquid level sensor
The submersible liquid level sensor measure the level of a water, wastewater, chemical or other liquid element in various industries. The device measure the level by hydrostatic pressure, the pressure exerted by the liquid height in the tank or sump. The Hydrostatic pressure determined two things: the density and height of the liquid. Liquid density remaining constant and the the pressure reflect with the liquid level changing. Submersible level sensors consist of a sensor attached to a long cable, which is then lowered to the bottom of the liquid tank.
​
The submersible level sensor transmits data as a 4-20 mA analog signal. This design provides for long stability, repeat-ability and high accuracy. The level sensor is easy to install and protected from liquid ingress when completely immersed in a liquid for measuring because the made up with 316 stainless steel, with a standard polyurethane cable and Viton seal.
A special cable support bracket is also available. This gives extra stability to the transducer when used with ling distance of cable or when used in an agitated liquid. A conduit adapter is also available.
​
The FT is also available calibrated for any span needed, from 0-6 PSI ( 0.4 bar, 14 ft or 4.2m of water) to 0 to 300 PSI (20 bar, 0-690 feet or 0-211 meters of water). Other optional outputs include 0.5 to 4.5 VDC, 1 to 5 VDC, 1 to 6 VDC, or 0 to 5 VDC.
​
Submersible Level Sensor is suitable for hazard environments and any size of sump or tank. The sensor sits at the lower level of a tank or sump. Based on the liquid height and density exerted the weight and the volume, can be determined. Down-hole Submersible Level Sensors can also use for continuous level measurement and environmental applications like ultrasonic sensors.
​
Any electrical based submersible level sensor that generate a signal of measurement can be connected to display where it can show the data which required for managing usage and supply. If the liquid tank is close by it may be more practical to generate the analogue signal and sent to digital interface.
