HD350 series | Ultrasonic Level Meter｜HD350-A / HD350-B
[Measurement Equipment [ Level meters ]]
●Wide measurement range
HD350-A and HD350-B covers different measurement range
HD350-A：0.3 - 10 ｍ
HD350-B：0.15 - 4 ｍ
●For screen mode can be selected
Unnecessary signal can be eliminated from the received signal by manually.
Echo signal from existing structure positioned between sensor and target cause interference. Mask function removes these unnecessary echo effectively.
Three interface methods are prepared for remote operation.
1) RS-485 (MODBUS protocol)
2) 4 - 20 ｍA current output
3) Contact points (relay output)
