▋ FAQ
1. Equipment measurement principle?
A: When the sensor is put into a certain depth of the measured liquid, the pressure of the measured medium is introduced into the positive pressure chamber of the sensor, and the atmospheric pressure on the liquid surface is connected to the negative pressure chamber of the sensor through the cable airway to offset the front of the sensor, so that the sensor can measure the pressure, and the liquid level depth can be obtained by measuring the pressure
2. What is the range of the equipment?
A: The default measuring range is 0 ~ 10 meters, and the larger measuring range needs to be customized.
3. What is the measuring accuracy of the equipment?
A: The measurement accuracy is not higher than 0.5%, such as 10 meters range, the accuracy is 5cm.
