To Make Your Selection, decide first between A) or B)
A) – I Want Digital Indication (Readout or Display)
Of Level Or Volume In My Tank.
A1 – I want to monitor several tanks on location = see SONIX-1000 (monitors up to 7 tanks) or UC-4000 (monitors up to 9 tanks). (Note – both can also have analog outputs and alarm relays.)
A2 – I want to monitor only one tank on location = see
UL-1000. (Note – has 2 alarm relays and can also have 4-20 mA analog output)
A3 – I want to monitor only one tank on location and control Pump or Valve = see LP-10. (Note – has latching relay, 2 alarm relays and can also have 4-20 mA analog output)
A4 – I want to monitor only one tank on location and also have 4-20 mA analog output = see UL-100.
B) – I Do Not Want Digital Indication (Readout or Display):
Sonix-40 or Sonix-50, level transmitter with 4-20 mA current output, 24 VDC power, push button calibration, for tanks up to 15 feet high.
Sonix-11, tank level switch with two alarm relays.
SoniGuard, monitors if chute is plugged, blocking flow of material. Also, hopper level control, high and low.
