How to choose the right type:

The selection of the instrument is a very important task in the application of the instrument. The relevant information indicates that 2/3 of the faults in the actual application are caused by incorrect selection or incorrect installation of the instrument. Please pay special attention.

Data collection

1. The fluid component to be tested;

2.zui large traffic, zui small traffic;

3.zui high work pressure;

4.zui high temperature, zui low temperature.



Installation and use:

1. The display mode, communication mode and data storage of the flow detection instrument are an important part of the instrument. Traditional electromagnetic flowmeters generally use LED or segment LCD in display mode, which can only display numbers, letters, Chinese characters and some rough patterns. In terms of data storage, information storage is generally stored in binary mode, without versatility and storage capacity. Small; in the communication mode, generally adopt RS232 or RS485, its openness is not high.

2. Sensor installation in vertical pipe

When measuring gas flow, the sensor can be mounted on a vertical pipe with unlimited flow. If the gas to be tested contains a small amount of liquid,

The gas flow should be from bottom to top.

When measuring the flow of liquid, the flow direction of the liquid should be from bottom to top: this does not add extra weight to the probe.

3, the sensor is installed on the side of the horizontal pipe

Regardless of the fluid being measured, the sensor can be mounted sideways on a horizontal pipe, especially for superheated steam, saturated steam and cryogenic liquids.

If the conditions permit, it is best to use side-mounted, so that the temperature of the fluid has less influence on the amplifier.

4. Sensor flipping in horizontal pipe

This installation method is generally not recommended. This method of installation is not suitable for measuring general gases and superheated steam. Can be used to measure saturated steam for measurement

High temperature liquids or situations where pipes need to be cleaned frequently.

5. Sensor installation on insulated pipe

When measuring high temperature steam, the insulation layer should not exceed one third of the height of the bracket.

6. In order to solve the above shortcomings, an electromagnetic flowmeter with informationization, graphics and networking has been developed using a 32-bit ARM processor and an embedded Linux operating system. It adopts T FT color LCD display mode, which can not only display flow data but also display flow curve, improve the quality and content of display; use JFFS2 file system to store data by file, and the storage capacity can reach 1MB.
