What is a rectangular flowmeter? Simply put, a rectangular flowmeter is a combination of a wedge flowmeter and a Venturi flowmeter. It is a differential pressure flowmeter. The throttling element inserted into the wedge-shaped flowmeter is triangular, while the throttling element inserted into the rectangular flowmeter is rectangular. After inserting the rectangular throttling element, the state of fluid passing through is similar to that of an eccentric Venturi tube. The characteristic is Brother Qi: it is not only suitable for circular pipelines, but also applicable to rectangular pipelines; The advantages of measuring mixed liquids containing solid particles with eccentric Venturi and wedge characteristics; Manufacturing is much simpler and cheaper than eccentric Venturi; The throttling element is not like a wedge-shaped flowmeter, as it does not face the scouring surface of the slag flow and is wear-resistant. 2. What types of flow meters are orifice flow meters, wedge flow meters, flow transmitters, etc? _Baidu Knowledge ..
Orifice plate flowmeter and ridge grip wedge flowmeter belong to constant cross-section, variable pressure differential flowmeter. Flow transmitter, not a flowmeter, belongs to secondary instruments and can be matched with various flow meters according to its form. There are various forms of flow meters, including mass type, velocity type, volume type, etc. There are about dozens of forms. You can refer to articles such as Baidus "Flow Meter" and "Quality Flow Meter" by Ye Bi.

5. How to install a wedge flowmeter?
1、 Generally, wedge-shaped flow sensors are equipped with front and rear measuring tubes, which can be installed and used horizontally or vertically. When the sensor is installed on a vertical pipeline, the fluid should flow from bottom to top. When measuring liquids, attention should be paid to ensuring that the differential pressure transmitter can easily eliminate bubbles to avoid instrument zero drift caused by disorderly failure;
2、 The upstream and downstream sides of the sensor should be equipped with straight pipe sections, and the inner wall of the pipeline should be smooth, clean, and free of attachments. The length of the pipe section should be as shown in the table. When installed horizontally, the wedge-shaped differential pressure element should be at a 90 degree angle to the centerline of the pipeline. For vertical installation, it is necessary to pay attention to the zero adjustment of the differential return absolute pressure transmitter due to the slight static vibration pressure between the pressure points.
