    Tips: Operating steps of start and stop a differential pressure transducer

    There are at least five valves connecting with the differential pressure transducer, among, two sampling valves are used for sampling and cutting off the process media, two blow-down valves are used to flush the connecting pipe or remove condensate or gas from the connecting pipe. The connecting pipes are connected with the differential pressure transducer through three-valve group or five-valve group, and the starting and stopping of differential pressure transducer are mostly operated on the three-valve group.

    1. Stop Method of Differential Pressure Transducer
      When closing the differential pressure transducer, the steps for closing the three-valve group are as follows: close the negative pressure valve first, then open the balanced valve, and finally close the positive pressure valve. If the differential pressure transducer is out of operation for a long time, both positive and negative pressure valves of primary valve and three-valve group should be closed, the balanced valve should be opened to ensure equal pressure on both sides of the transducer's measuring room, in a balanced state.
    2. Start Method of Differential Pressure Transducer
      When starting the differential pressure transducer, the steps for opening the three-valve group are as follows: open the positive pressure valve firstly, then close the balanced valve, and finally open the negative pressure valve.
      When starting or stopping the differential pressure transducer for steam flow measurement, the differential pressure transducer with isolator, and the liquid level differential pressure transducer with a balanced container, the positive pressure valve/negative pressure valve/balanced valve cannot be opened at the same time when operating the three-valve group. Because even if it is opened in a short time, the condensate water in the balanced container and the isolation fluid in the isolator may run off, resulting in the incorrect display of meter, and even the differential pressure transducer cannot be put into operation in serious cases. When necessary, the drain valve and exhaust valve on the measurement room of differential pressure transducer shall be used to remove the air or condensate water.

    Existing reviews of Differential Pressure Transducer, Output 4-20mA HART
    High quality differential pressure transducer
    I bought a differential pressure transducer some time ago. ATO's service is very good. I decided to order another 4-20mA HART differential pressure sensor.
