Overall dimension

Instrument installation

The sensor shall be installed on the horizontal, vertical, inclined (liquid flow from bottom to top) pipeline with the same diameter. The upstream and downstream of the sensor shall be equipped with a certain length of straight pipe section, which shall meet the requirements of 15~20D for the front straight pipe section and 5~10D for the rear straight pipe section. The pipeline near the liquid sensor shall be filled with the measured liquid. The sensor shall not be installed on the pipeline with strong mechanical vibration. The inner diameter of the straight pipe section shall be consistent with the diameter of the sensor as much as possible. If it cannot be consistent, the pipe slightly larger than the diameter of the sensor shall be used, and the error shall be ≤ 3%, not more than 5mm. If the measured medium contains many impurities, a filter shall be installed beyond the length required by the straight pipe section upstream of the sensor. The sensor shall not be installed in places with strong electromagnetic interference, small space and inconvenient maintenance.

Summary

On-site display vortex flowmeter has the characteristics of miniaturization, micro-power consumption, intelligence, etc., realizing the measurement, display and integration of flow parameters. The field display instrument is used in an environment where the power supply is not convenient: the instrument is designed with an ultra-low power consumption chip, which is convenient to operate, and is at the leading level among similar domestic products.
