Abstract: V-cone flow meter on-site installation experience summary information is provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. Today, I received a response from a customer on site, saying that when a V-cone flowmeter ordered by another company was put into use, the differential pressure transmitter displayed a negative differential pressure value on site. At first we thought this situation was a very simple problem, because according to past experience, it was basically OK. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the summary of the V-cone flowmeter meter site installation experience summary article details. Today, I received a response from a customer on site, saying that when a V-cone flowmeter ordered by another company was put into use, the differential pressure transmitter displayed a negative differential pressure value on site. At first we thought this situation was a very simple problem, because according to past experience, it can basically be determined that it is a problem with the wiring of the positive and negative pressure chambers of the differential pressure transmitter, but the customer responded that the on-site differential pressure transmitter uses 3051 transmission. It has been ensured that there is no problem with the device, wiring and zero calibration. This is very confusing to us. Finally, after communication, it can be roughly determined that it is the measurement problem of the V-cone flowmeter. The following is the inspection plan determined for the customer: 1. First, check the problem of the positive pressure suction pipe of the V-cone flowmeter. To ensure that the pressure suction pipe is unblocked. Check for leaks and plugs, because if such a problem occurs, the differential pressure transmitter will be pressurized in one direction, which will cause the above-mentioned negative pressure phenomenon. 2. The second problem is more serious, that is, the manufacturer of the positive pressure port of the V-cone flowmeter body has not done a good job. On this issue, we have also communicated with the technical staff of our own manufacturer. If the positive pressure port welder technology is not done well, then That is to say, the positive pressure taking in disguised form is not smooth, and the principle of leakage is basically the same as above. In view of the above situation, the following will introduce how to solve it. In view of the problem of leakage of the pressure tap, it is relatively convenient to check, directly inject the gas, and observe the current status of the pressure tap; and if it is a welding problem, then this is troublesome. If you are familiar with the body of the V-cone flowmeter on site If it is not possible, the V-cone flowmeter should be returned to the manufacturer for inspection and rework. (end) The above is the entire content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
