Choose a water level transmitter to transmit a 4-20 milliamp current signal using two wires for both power supply and signal. Underground rain water storage tank level sensor and readout for 2 metre depth-Water level indicator for a 2 metre deep rain water storage tank located underground.
A 4-20mA output hydrostatic level transmitter is commonly used as part of an on-site control & monitoring system to manage quantity of liquids and ensuring minimum and maximum liquid levels are not exceeded. Select a 4 to 20 mA current output hydrostatic level sensor for controlling a pump in a borehole or managing the contents of liquid ...
These hydrostatic liquid level sensors will measure from 0 to 2 metres of water column or 0 to 6 feet of water column liquid level ranges, and convert the measured level to a corresponding output signal from 4 to 20 milliamps, 0 to 10 volts, or 0 to 5 volts.
Each submersible pressure transducer has a two-wire 4-20 mA output signal linear with water depth. From 10 to 36 VDC is required to operate the water level sensor so that the level sensors can be operated from common 12 VDC battery systems.
The simplest and oldest industrial signal communication is 4-20 mA current loops (where the loop current varies with the level measurement) are the most common output mechanism today. Current loops can carry signals over longer distances with less degradation.
The general purpose ultrasonic level transmitter provides continuous level measurement up to 9.8’ (3m) with a 4-20 mA signal output and four relays, and is configured via our free WebCal software.
Robust ceramic pressure transducer for water level measurement. The OTT PLS, SDI-12 or 4 ... 20 mA pressure probe, measures water level, depth to water, or pressure using an integrated controller and ceramic pressure-measuring cell.
