What are the installation requirements for flow meters?

The installation requirements for flow meters are as follows:

1. The installation location should not have a large vibration source, and reinforcement measures should be taken to stabilize the pipeline near the instrument.

2、 Cannot be installed near large transformers, motors, pumps, and other equipment that generate large magnetic fields to avoid interference from electromagnetic fields.

3、 When connecting sensors to pipelines, full pipe operation should be ensured, and it is best to install them vertically.

4、 The transmitter housing, shielded cable, measuring body, and pipelines at both ends must be grounded. The grounding electrode should be set separately, and the grounding resistance should be less than 10 ohms. It cannot be connected to the electrical or public grounding network.

5、 Require a straight pipe dust collection section with a diameter of the first 5 times and then 3 times the diameter of the pipeline.

5、 The flowmeter can be installed horizontally and vertically, but it should be ensured to avoid the influence of sediment and bubbles on the measuring electrode, and the electrode axis should be kept horizontal. When installed vertically, the flow chamber should flow from bottom to top.

2. Does the sludge electromagnetic flowmeter have an impact on variable diameter installation?

The commonly used Ziyou Instrument series sludge electromagnetic flowmeter needs to consider the following before selecting a variable diameter installation: First, like other flowmeters, although the measurement range ratio of the electromagnetic flowmeter is 30:1, which is higher than that of the vor

tex flowmeter and differential pressure flowmeter, it is also limited. Many customers carry it with them when ordering a meter, often comparing it with a water meter, thinking that it can measure very low flow rates. In general, it can only measure 0.1m/s. Below this flow rate, it is difficult for the electromagnetic flowmeter to correctly measure the flow rate.

. So in the initial stage of ordering, it is necessary to clarify the flow range. When placing an order, it is not advisable to order according to the original pipe diameter. It is better to determine the instrument diameter based on your actual flow rate. 2、 Like other fiber flow meters, electromagnetic flow meters also have requirements for straight pipelines before and after installation, although the requirements are lower than other types of flow meters. However, the most crucial point is to meet the requirement of filling the pipeline before and after. 3、 Like other flow meters, electromagnetic flow meters also have protection levels. Generally, the protection level for integrated flow meters is IP65, and for split type flow meters (for sensors) it is IP68. If customers have requirements for the installation environment of the instrument and the installation location is in underground manholes or other humid places, it is recommended that customers choose split type flow meters. To avoid selecting the wrong one and causing damage to the instrument. 4、 Electromagnetic flow meters can measure corrosive liquids, but in the initial stage of ordering, customers need to provide the correct properties of other measuring media to avoid errors in electrode selection during selection, which may result in the sensor being scrapped during later use, causing inconven
