How to choose a proper ultrasonic level meter/ultasonic transducer
The structure of ultrasonic level meter
The compact version: The host and the probe are integrated;
The remote version: The host and the probe are separated.
The wire
Two-wire system:
It is standard ultrasonic distance sensor which power supply (only DC24V)and signal output (DC4-20mA)use same current loop; Two wires are enough.
Three-wire system:
Three-system is four-system in fact; Either the power supply or (4-20mA) signal output uses one separate current loop. When negative is with same ground reference, then three wires are enough. Its advantage is strong transmitting power.
Four-wire system:
Either the power supply or signal output (4-20mA) uses one separate current loop. Its advantage is strong transmitting power and provides high and low relay output.

Measuring range
The ultrasonic transducer select model number according to actual range. Select model number with bigger range if medium level fluctuating strongly. The range of solid level is generally one-half to two-third of that of liquid.
Power supply
DC24V power supply:
For two-wire system, the power supply current should not be less than 30 mA. For three-wire system, the power supply current should not be less than 60 mA.
For four-wire system, the power supply current should not be less than 80 mA.
AC220V power supply:
Only for four-wire system, the power supply current should not be less than 50 mA.
