1. The difference between ultrasonic energy meter and electromagnetic energy meter
The commonality between the two types of flow meters is that they can measure liquids and require the pipeline medium to flow through the pipeline.. The difference is that an ultrasonic flowmeter measures a uniform medium without impurities, while an electromagnetic flowmeter allows for impurities in the medium and can choose an inner lining based on the specific medium; The accuracy of the ultrasonic flowmeter is 1.0, and the accuracy of the electromagnetic flowmeter is 0.5; San Xians ultrasonic waves can be either externally attached or inserted, without the need to damage the pipeline. Electromagnetic connections are mostly flange or clamp connections, which require the destruction of the pipeline; Thirdly, the measurement principles are also different; This section is quite lengthy, so I wont go into detail here.
2. What are the reasons for the large fluctuations in electromagnetic flow meters?
There are generally various reasons for the large fluctuations in electromagnetic flow meters, such as when there is no flow. The main reasons for the large fluctuations are as follows:
1. There are some interference factors near the instrument, such as motors, frequency converters, etc;
2、 There is a problem with the circuit;
3、 It is possible that the grounding is loose;
4、 The air traffic control alarm

1. Incorrect installation position. Not satisfied with the pipeline, or gas residing in the pipeline system, or inhaling bubbles; Installed on a vertical pipeline from top to bottom, there may be reasons such as emptying.
2、 If a liquid contains uniformly distributed small bubbles, it will not affect normal measurement. However, if the measured volumetric flow rate is the sum of the liquid and gas, the increase in bubbles will cause fluctuations in the output signal.
3、 Medium fluctuations or pulsations.
4、 The electrode is contaminated or the electrode suitable for the measured liquid is not selected correctly. In order for the Huaishang electromagnetic flowmeter to perform its efficient and accurate measurement function, it is necessary to pay attention to instrument maintenance and regularly check the working condition of the instrument. Discovering problems and finding solutions in a timely manner will not cause greater losses. Kind reminder: The above content is for reference only. Response time: September 29, 2021.
