Application places and specific analysis of sewage flow meter

Application sites and specific analysis of sewage flow meters

It has the characteristics of low measurement flow rate and wide range ratio, and is widely used in chemical industry, steel, coal, mining and metallurgy, petroleum mining, petrochemicals, papermaking, and environmental protection, sugar refining, pharmaceuticals, food, water conservancy irrigation, water supply and drainage and port dredging and other fields, can accurately measure various acids, alkalis, salt solutions, raw water, cooling water, sewage, coal slurry, ore slurry, mud, cement slurry, paper pulp, Volume flow rate of conductive fluids and solid-liquid two-phase bodies such as syrups, liquid medicines and various beverages.

Detailed analysis of sewage flow meters

It is widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, and environmental protection and people's daily life and other fields of the national economy. It is an important tool for developing industrial and agricultural production, saving energy, improving product quality, improving economic efficiency and management level. It occupies an important position in the national economy.

What should we pay attention to when installing a sewage flow meter?

1. The sewage flow meter should be installed at the lower and vertical points of the horizontal pipeline, and avoid installation at the high point and vertical point of the pipeline;

2. The sewage flow meter It should be installed at the rising point of the pipe;

3. When installed in the open discharge pipe, it should be installed at the lower part of the pipe;

4. If the pipe drop exceeds 5m, the sensor should be installed at the lower part of the pipe. Install an exhaust valve downstream;

5. The sewage flow meter should be installed with a control valve and a shut-off valve downstream of the sensor, and should not be installed upstream of the sensor;

6. The sensor cannot be installed It should be installed at the inlet and outlet of the pump;

7. How to install an electromagnetic flowmeter in the measuring well.

The specific analysis of sewage flow meters is as follows:

1. Safety: When selecting and installing the instrument, you must consider its safety rules, such as whether the installation environment has explosive threats;

2. Ambient temperature: Changes in the ambient thermometer will have a greater impact on the electronic components of the instrument and some flow detection parts of the instrument; if the flow characteristics are affected by changes in ambient temperature, some pipelines need to be outsourced with thermal layers;< /p>

3. Environmental humidity: If the ambient humidity is increased, electrical insulation will be reduced, and atmospheric corrosion and electrolytic corrosion will be accelerated. If the ambient humidity is reduced, static electricity will easily occur; therefore, problems caused by humidity , for the possible range of changes, users should anticipate and verify whether unnecessary problems will occur during the operation of the selected instrument;

4. Electrical interference: Electrical electromagnetic interference usually occurs in power This is also a source of measurement errors in cables, electrical switches and motors.

Sewage flowmeters have lower requirements for measurement media, and their scope of application is getting wider and wider. They are more convenient to use and are becoming more and more fool-proof to achieve intelligence. The reliability of the product has been greatly improved.
