Crystal type water level meter (RS485 type) QSM series
Takuwa
About This Product
This device is a pressure -type water level meter that detects water levels from water pressure. The water level can be measured at a high precision to use the crystal vibration for pressure detection.
The frequency of the crystal vibrator is converted to a water level and outputs at the serial signal of the RS-485.
･ The setting value is memorized in the sensor and the sensor setting after installation is not required.
･ RS485 is used to transmit up to 1.2km long distance.
･ RS485 achieves noise strong transmission performance.
