Ultrasonic sensor for Level Meter |
|
| |
|
| This product is High Frequency Ultrasonic Sensor that uses piezoelectric ceramic and the skill of sound conformity in the air. It is the ultrasonic sensor for the high accurate measurement device.
|
| |
- Transmit/receiving combined sensor
- By using epoxy type sound layer, it has the excellent ability to bear the high temperature
- With excellent reception, measuring range is very broad
- With narrow beam angle, you can prevent wrong movement |
|
 USES |
| |
- Ultrasonic level meter for the sewage disposal plant,
service reservoir and others
- Open channel type flow meter,
bridge and river surface meter
- All kinds industrial factory's water disposal and liquid
tank's level meter
