The steam flow meter is a special meter for measuring the cumulative mass flow of steam, and is suitable for the measurement of high temperature and high pressure steam, boiler outlet, superheated steam or saturated steam of a steam pipe network. Widely used in petroleum, chemical, textile, heating and other occasions need steam flow meter.
The installation of the flow meter is an important guarantee for normal operation and accurate measurement in later use. If the installation is not correct, we will not be able to obtain accurate measurement results in the future measurements, and serious damage will be caused to the instrument. Some of the conditions for the correct installation of steam meters today are briefly described.
1. The sensor should be installed in places with strong electromagnetic field interference, small space and inconvenient maintenance.
2. The sensor should not be installed on pipes with strong mechanical vibration. The nearby pipeline where the liquid sensor is installed should be filled with the liquid to be measured.
3, the sensor should be installed on a pipe with strong mechanical vibration.
4, the sensor should be installed in the horizontal, vertical, tilt (liquid flow from bottom to top) on the same diameter as the pipeline. The upstream and downstream of the sensor should be equipped with a straight pipe section of a certain length. The length of the straight pipe section should be consistent with the requirements for the straight pipe section 15 to 20D and the straight pipe section 5 to 1 OD.
5. When the measured medium contains more impurities, a filter should be installed in addition to the required length of the straight section upstream of the sensor.
6. The inner diameter of the straight pipe section should be the same as the sensor diameter as much as possible. If it is not consistent, a pipe with a diameter slightly larger than the sensor should be used. The error should be ≤3% and does not exceed 5mm.
