How to obtain the best measurement method when using an orifice flowmeter

Author:    Source:    Date: 2021-05-27 14:58:51
The intelligent throttling device (orifice flowmeter) is a new generation flowmeter, which integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. The orifice flowmeter adopts advanced microcomputer technology and new micro-power consumption technology, with strong functions, compact structure, simple operation and convenient use
In order to obtain the best measurement results, the following conditions should be considered:

1. When wiring, pass the cable through the waterproof connector (accessory) or hose, and tighten the sealing nut to prevent rainwater from passing through the cable
2 When leaking into the transmitter housing and measuring the liquid pressure, the installation position of the transmitter should avoid the impact of the liquid (water hammer) to avoid damage to the sensor due to overvoltage
3. When freezing in winter, the orifice flowmeter installed outdoors should take anti-freezing measures according to the required pressure to prevent the liquid in the pressure port from expanding due to the frozen volume and causing damage to the sensor
4. Prevent sedimentation in the pipe
5. The pressure pipe should be installed in a place where the temperature is low and the fluctuation is small

6. When measuring the liquid pressure, the pressure measuring port on the side of the process pipeline should be opened to avoid slag accumulation
7. Prevent the orifice flowmeter from contacting corrosive or overheated media
8. When measuring gas pressure, the pressure measuring port should be opened at the top of the process pipeline, and the transmitter should also be installed on the top of the process pipeline to facilitate the injection of accumulated liquid into the process pipeline
9. When measuring steam or other high-temperature media, a buffer tube (coil) and other condensers should be added. The operating temperature of the transmitter should not exceed the limit
