Should an electromagnetic flowmeter be installed in the water supply or return line?

Case introduction

1. Introduction

As a widely used logistics meter, electromagnetic flowmeter is very popular among users for its accuracy and stability. When using electromagnetic flowmeters, the choice of installation location is very important, because the installation location directly determines the accuracy of the measurement results. So should the electromagnetic flowmeter be installed in the water supply pipe or the return pipe?

2. The influence of installation position on measurement accuracy

As a non-intrusive measuring instrument, electromagnetic flowmeter can usually be placed outside the pipeline. The choice of installation location has an important impact on measurement accuracy. In a closed pipe, there will be a certain resistance when the water flows in the direction and reverse direction, so the flow rate measured in the water supply pipe and the return pipe will be different.

Due to the different pressures of the water supply pipe and the return pipe, installation on different pipes will produce different measurement errors. In order to ensure accuracy, it is very important to choose different installation locations according to the actual situation.

3. Advantages and disadvantages

Installation in water supply pipes and return pipes has its advantages and disadvantages. Installed on the water supply pipeline, it can quickly detect the water consumption in the pipeline, but it is greatly affected by the fluctuation of water supply pressure and can easily cause errors. Installed on the return water pipe, although it is easily affected by bubbles and causes inaccurate measurement, it is more stable than installed on the water supply pipe.

IV. Recommendation of installation location

Based on comprehensive considerations, in order to ensure accuracy and stability, it is recommended that the electromagnetic flowmeter be installed on the return pipe. If you need to quickly monitor water consumption, add a flow meter to the water supply line for monitoring.

5. Summary

When using electromagnetic flowmeter, the installation position has a great influence on the accuracy and stability of the measurement results. It is very important to choose the appropriate installation location according to the actual situation. In order to ensure accuracy and stability, it is recommended to install the electromagnetic flowmeter on the return water pipe.
