Electric wiring diagram of ultrasonic level difference meter and wiring
terminal diagram:
Wiring method:
Grounding: first make sure the grounding terminal of the meter is actually
grounded and the meter does not share ground terminal with other equipment
and then connect terminal 4.
Transducer: red line: connected to Trans_n transducer n; blue line: Temp n +
temperature
Black wire: GND (ground wire)
For single probe, n =1; for double probes, n = 1,2
Current: c connected to mA n+; current - connected to mA n- /GND
For single probe, n =1; for double probes, n = 1,2
Relay: RLlnA and RLnB are normally open; RLnA and RLnC are normally
closed
For single probe, n =1.2; for double probes, n= 1,2,3,4
