When companies select flowmeters, many companies will choose Coriolis mass flowmeters at reasonable cost. When installed correctly, Coriolis mass flow meters can directly measure the mass and density of the fluid, and only a reasonable installation can ensure the accuracy and stability of the mass flow meter.
1, Coriolis mass flowmeter installation routine points
There must be a minimum distance of 0.6m between the sensor and the larger transmitter or motor. Since the sensor operation depends on the electromagnetic field, it must be avoided to install the sensor near a large interfering electromagnetic field. In addition, you should carefully select the installation location to avoid vibration.
2, the installation direction
The requirements of the process and the location of the well-arranged process piping determine the orientation of most sensors. Although the installation angle of the sensor does not affect the operation of the flowmeter, the following recommendations should be considered as much as possible:
(1) When measuring liquids, the sensor housing should be mounted downwards to prevent air from accumulating in the flow tube;
(2) When measuring gas, the sensor housing should be installed upwards to avoid condensing water in the flow tube;
(3) When measuring the liquid slurry, the sensor should be installed vertically, like a flag, to prevent particles from accumulating in the flow tube. The process medium should flow from bottom to top to avoid spouting empty tubes.
3, valve
To make the flowmeter zero, a stop valve should be installed downstream of the sensor. For ease of batch operation, the sensor and shutoff valve should be as close as possible to the receiving container. No hose should be installed between the sensor and the shutoff valve to avoid batch errors due to expansion or compression. In addition, a regulating valve can be installed downstream to prevent vaporization or evacuation of the medium.
4, the flow of mass flow meter installation
Whatever the direction of flow, the flow sensor can accurately measure the flow. The arrow on the general sensor indicates the normal flow of the fluid.
5, gas-liquid two-phase flow
If the process medium produces a gas-liquid two-phase flow, the sensor housing should be mounted face down or on a vertical pipe. This installation method can effectively prevent the gas in the medium from accumulating in the flow tube.
It is worth noting that in load and unload metering applications, the sensor housing should be mounted face up or vertically. A one-way valve should be installed downstream of the sensor to prevent backflow of the medium. The check valve should be installed as close as possible to the sensor. In some cases, the process media can not be completely excluded from the pipeline, flag-type installation is generally recommended at this time.
When the Coriolis mass flowmeter is installed, the direction of installation is very important. The direction of installation is determined by the location of the well-arranged process piping on the site. A reasonable installation can ensure the long-term stability of the Coriolis mass flowmeter. work.
