The Well Watcher
A submersible hydrostatic pressure transmitter system that has had wide acceptance and use in water well level measurements. It is price and performance competitive with Druck and KPSI submersible pressure transducers. 

The model 750 Series submersible transmitter 
A two-wire, 4-20mA, system that comes factory calibrated over the desired level measurement span. The linear 4-20mA signal is driven by the Well Watcher’s 24VDC loop power. The analog signal from the “down-well” transmitter feeds a microprocessor based digital display with configurable 2 relay outputs (SPST) for pump control, optional analog outputs and/or RS-232 outputs (for printer). 

No Calibration
Similar to recent new product designs and introductions, the Well Watcher requires no calibration. The linear 4-20mA transmitter signal is factory calibrated over the full range of the submersible hydrostatic level transmitter. If the analog output option is chosen the programmable 4-20mA signal and display will be factory calibrated over the customers desired level measurement span.
