Q
What is the liquid material of the sensor?
AThe liquid material is different for each product, and most of the material is POM.
-
Q
The sensor returns no data. What is the cause?
ACommunication problem, please check the power supply, 485 line, and equipment.
-
Q
What is the difference between 4-20MA and RS-485?
ACables passing through 4-20mA will have loss, so there will be deviation on the value. 485 is not affected by the cable length, and 485 is the current trend. Can be made 485 and 4~20mA two output mode.
-
Q
What is the sensor made of? Can it be made of 316L material?
AThe shell is basically POM, and 316L material is available at present.

Q
Secondary water supply module
ASecondary water supply mainly monitors residual chlorine, PH, turbidity and flow rate. Scenario Secondary water supply and drinking water supply.
-
Q
The sensor data is 0. What is the reason?
AIf the conductivity is 0, it may mean that there is no contact with water, and if the COD is 0, it may mean that the turbidity is full scale. The specific sensor is 0, and the situation may be different. If it is encountered, please contact our after-sales service.

Q
What's the difference between your sensor and one with a watch head?
AOur sensor is 485 output, better integration.
-
Q
Can the power supply range of sensor 10.6-16.8V work properly?
AYes, the minimum operating voltage is 9V and the maximum is 32V.
-
Q
What is the difference between pH, turbidity and residual chlorine?
APH is the same as residual chlorine, turbidity is a cylinder circulation pool, which will be treated to avoid light.
-
Q
How to install the inlet and outlet water pipe of water station?
AThere is no big requirement, it is suggested to do filtration at the intake.
-
Q
What are the characteristics of the sensor? What are the advantages over other company sensors?
ASmall size, low power consumption, anti-interference, 485 output integration.
-
Q
What is the power consumption of the sensor? Is there a dormant period?
AGenerally less than 0.5W, real-time online.
