Tank Level Sensor Pressure

Measure liquid level within a vented tank using a submersible pressure transducer.

Tank level sensor pressure.

By using a liquid s specific gravity and column height pressure is easily determined. Since a pressure transmitter provides a linear output signal e g. However it may be necessary to create a new tapping point especially if there is a high flow rate suction or positive pressure at the outlet or. A gauge sensor used in the hydrostatic method of measuring tank level employs simple physics to produce high accuracy readings.

There are floating sensors such as magnetostrictive level sensors which use an electrical signal to pinpoint the location of magnetic float on a vertical guide. 4 to 20ma signal from zero pressure to the full scale pressure the level can be monitored based on the liquid density and the height of the tank. Our tank level sensors are both cost effective and compatible with a range of liquids and do not have issues related to reflection or foaming. In order to measure the fluid level a hydrostatic pressure sensor should be mounted at the lowest required measurement point which could be an outlet or inlet for example at the bottom of the tank.

The actual shape of the tank is only needed when a customer uses the liquid level to calculate volume. Non pressure level sensors come in a few variations. There are ultrasonic and laser level sensors which use sound or light waves to measure the distance from the sensor to a surface.
