The Delta Controls Model 590 level transmitter incorporates both the sensor and the electronics unit in a single potted module. The module is protected by a sealed stainless steel case. This lower body is sealed to an electrical cable, both of which are supported from the well head above. The sensor detects the pressure of the water surrounding it. This pressure is linearly proportional to the height of water above it. The sensor/electronics unit converts the pressure into a 4-20 mADC signal equivalent to the liquid level.
Unlike "Capacitance" and "Admittance" type devices, the Model 590 is unaffected by algae growth and sludge coating. Also, it's calibration can be "bucket" checked or changed without the unit being installed in a well or basin. It is inexpensive to purchase and install. It is also virtually maintenance free which results in a low cost of ownership.
The Model 590 is also very useful for measuring levels in elevated and ground storage tanks. The flexible cable is easy to handle and install in every application. The small body diameter allows it to be installed in a well casing, through a 1" protective guide pipe, or a tank vent pipe.
