Level Measurement

See below for our complete level sensor products including, hydrostatic level sensors, level transmitters and levels gauges typically using the hydrostatic principle.

The level sensors include submersible level transmitters or screw-in type level transmitters with either digital or analogue outputs including 4-wire millivolt, voltage or 4-20mA current, SDi-12, RS485, HART and i2c.

 

Submersible level sensors and level transmitters

Submersible level sensors and level transmitters

Submersible level sensors and transmitters make it very easy to measure the depth of water such as the level of a tank, depth of a river or level of water in a borehole. The sensor is simply suspended by its strain relieved cable to the bottom of the tank, borehole or river and it will measure the hydrostatic pressure created by the liquid above the sensor.

As a rough guide approximately 1m of water = 100mbar of pressure. This is then converted into an electrical signal used to calibrate an accurate level measurement in the tank/river/reservoir/borehole.

Screw-in level transmitter

Screw-in level transmitter

If you do not require a submersible level sensor or transmitter, you can simply screw these devices into the bottom or side of the tank/pipework by their threads and this will enable the sensor to measure the hydrostatic pressure created by the liquid above the sensor, approximately 1mWG is around 100mbar. We can use this pressure measurement to convert to a level reading.

For different density liquids, the specific gravity of the media can be considered for accurate level readings. Combining a screw-in level transmitter with a temperature sensor will allow you to dynamically adjust the specific gravity should the liquid have a specific profile that is followed when the temperature changes. We can take this temperature measurement and pressure measurement (level) into a dual-channel device such as the CMC-N16 and use the maths channels to create a true level measurement reading.
