Drainage flowmeter, sewage outfall flowmeter installation position

Electromagnetic flowmeter is based on the principle of electromagnetic induction, through the electromotive force generated by the conductive fluid through the external magnetic field to measure the fluid flow meter. Electromagnetic flowmeter is widely used because of its high precision and good stability, so the choice of integrated or split electromagnetic flowmeter is particularly important.

What are the advantages of electromagnetic flowmeter measurement for sewage measurement? The plug-in electromagnetic flowmeter is composed of two parts: flow sensor and transmitter.

In the metering industry, electromagnetic flowmeter is a basic metering tool, and its range of use is very wide. The emergence of electromagnetic flowmeters has made great contributions to many industries, and it occupies a very important position in these industries. Pay more attention when using the electromagnetic flowmeter, check it before use to see how accurate its measurement is. The calibration of electromagnetic flowmeter is mainly considered from the following aspects:

With the speeding up of urbanization process in our country, environmental pollution is increasingly serious. Because in sewage treatment, it is necessary to analyze and control the discharged sewage, additives, sludge, etc., so the flow measurement is very important. Among the many flowmeter products used for sewage measurement, electromagnetic flowmeter measurement accuracy is higher.

The electromagnetic flow meter consists of a non-conductive pipe lined with a conductive material, typically made of metal. The meter contains coils or electrodes positioned opposite each other on the pipe’s inner walls. A magnetic field is then generated by passing a current through these coils, creating a measurable voltage across the fluid. The induced voltage, or EMF, is directly proportional to the fluid’s velocity, allowing the flow meter to accurately determine the flow rate. Importantly, this principle remains effective regardless of the fluid’s conductivity, making electromagnetic flow meters suitable for a wide range of applications, including water, wastewater, and various industrial processes.

Electromagnetic flowmeter grounding problem

Impurities in the medium flowing through electromagnetic flowmeters can have several effects on their performance and accuracy. While electromagnetic flowmeters are known for their versatility and ability to handle a variety of fluids, the presence of certain impurities may impact their operation.

Selecting the appropriate installation point for an electromagnetic flowmeter is crucial for accurate and reliable measurements. Here are some considerations and guidelines to help you choose the right measuring installation point:

1. The sensor structure of the electromagnetic flowmeter is simple, and there are no moving parts in the measuring tube, nor any throttling parts that hinder the flow of fluid. So when the fluid through the flow timing will not cause any additional pressure loss, electromagnetic flowmeter is a very low energy consumption flow meter.

The reason why the measurement error is large is that the amount of oil and suspended matter in the water from the sewage station is high, and the treated sewage has a small amount of oil and suspended matter in the water, and the error of electromagnetic flowmeter measurement is also small.
