Technical field

The invention relates to a flow rate detection equipment, in particular to a flow rate detection instrument applied in high-frequency vibration working conditions.

Background technique

The flow rate detector is an instrument used to measure the velocity of the fluid in the pipeline. After the flow velocity is measured, it is multiplied by the fluid cross section to convert it into a flow rate, which is also used to indirectly measure the flow rate. There are velocimeters, orifice flow meters, speed nozzles, and Venchenli flow meters.

With the continuous increase in anti-pollution and pollution control efforts, the regular collection and testing of sewage has become more and more stringent. However, the existing sewage detection mode mainly relies on the sewage in the sewage tank to be pumped into the testing equipment for sewage detection. When testing the sewage drainage pipeline on the ground, the extraction method is often not used because the extraction process is not easy and the sewage content after extraction is high. Therefore, the sewage detection of ground drainage pipes generally involves drilling holes around the drainage pipes, and then installing the sewage detectors. The sewage detectors here are suitable for high-frequency vibrations caused by rapid water flow or large-scale mechanical construction. condition.

Existing flow rate detectors, in the detection of sewage discharged from industrial plants, are likely to cause the large solid matter contained in the sewage to collide with the flow rate detection device due to the excessively fast flow rate of the sewage in the drainage pipe, causing the flow rate detection device to be damaged.
