• Q

    How to install the inlet and outlet water pipe of water station?

    A

    There is no big requirement, it is suggested to do filtration at the intake.

  • Q

    What's the difference between your sensor and one with a watch head?

    A

    Our sensor is 485 output, better integration.

  • Q

    What are the ways in which sensors transmit data?

    A

    At present, there are two kinds: the first kind is through the computer, PLC, EXO-202 and so on in the way of wiring to send data query instructions to the sensor, sensor response data through cable transmission to the computer, PLC, EXO-202, the response data can be converted into the test data, the computer needs software is serial debugging assistant.  The second method is to realize wireless transmission through DTU and RTU. DTU generally requires the cooperation of front-end devices. For example, DT-200 is responsible for data collection and DTU is responsible for data transmission, while RTU can realize both collection and transmission functions.  If we want to find the data from the server, we need the corresponding computer software and mobile phone software, or we can send the data to the client server, and the client can write the software to realize the data query.  

  • Q

    What is the power consumption of the sensor? Is there a dormant period?

    A

    Generally less than 0.5W, real-time online.

  • Q

    Do I need to recalibrate it right away?

    A

    The sensors have been calibrated from the factory and can be used directly. Some sensors need to be carried out or activated.  

  • Q

    What are the requirements for the location of water stations?

    A

    The shore is relatively flat, usually the water level will not have a place.

  • Q

    What are the characteristics of the sensor? What are the advantages over other company sensors?

    A

    Small size, low power consumption, anti-interference, 485 output integration.

  • Q

    About the problem of uploading DTU data to the server established by the customer.

    A

    The data can be uploaded to the client server for validation.  The DT-200 collects the data from the connected sensor and sends the data to the DTU. The DTU then sends the parsed data to the server.  The data is uploaded to the server in the following format:  

    1devid:10000,ecm:1455.4,tmp:24,5,rdo:10.36,tmp:15.3,ecs:281.9,tmp:24.4,phg:3.4,tmp:28.7,nul:0,tmp:0,nul:0,tmp:0,nul:0,tmp:0,nul:0,tmp:0,nul:0,tmp:0,nul:0,tmp:0,nul:0,tmp:0,nul:0,tmp:0,end

  • Q

    How do I read the sensor once I get it?

    A

    You can use our free computer software, or do your own integration.

  • Q

    How to store sensors?

    A

    Store according to shipment, out of light.

  • Q

    What equipment does the water station contain? What are their functions?

    A

    What equipment does the water station contain? What are their functions?

  • Q

    If the RS-485 protocol fails somewhere, does the device still work?

    A

    The integrated sensor normally does not have a problem with the RS-485 protocol somewhere. The address of a single sensor on the integrated device is fixed and not the same. Even if a communication exception is caused by a failure, the whole device will not be affected.  
     
    If the customer integrates, the above problems may be caused by the same address of multiple sensors.  If the communication protocol is abnormal, power-on will not communicate.  The default data formats for RS-485 communication are 9600, N, 8, and 1 (baud rate 9600 BPS, 1 start bit, 8 data bits, no check, and 1 stop bit).
