How to choose a sewage flow meter

First of all, generally in the choice of flowmeter, will consider the accuracy level, easy to install and use, product price, and quality after-sales and other issues. According to the installation and use, accuracy level and other aspects to choose, electromagnetic flowmeter is very suitable. There are 2 main aspects, one is the installation is very simple, flange connection, the second is the accuracy, electromagnetic flowmeter can reach 0.5 level, or even 0.3 level accuracy. Of course, to ensure that the flowmeter is good to use, in the selection and purchase of the time must be and the manufacturer to provide the necessary parameters, only in this way can ensure the practicality of the flowmeter. In the customer selection time need to provide the following parameters:

• 1. Medium temperature;
• 2. Medium pressure;
• 3. Medium small flow rate, common flow rate, large flow rate;
• 4. The degree of corrosiveness of the medium;
• 5. Continuous or intermittent pipework;
• 6. The ambient temperature of the instrument installation;
• 7. There is no high power equipment around the meter;
• 8. Problems with instrument power cable routing.

Electromagnetic flowmeter manufacturers to raise the issue:

• 1. Selection of instrument power supply (battery power, 24V, 220V).
• 2. Instrument signal output: 4-20MA, 0-10MA, other signals and so on.
• 3. Meter display mode (with and without display).
• 4. Meter accuracy class.

Electromagnetic flowmeter modelling must be considered when the steam flowmeter range is not in the instrument range, and pay attention to the impact of small flows on the measurement of the table, to determine the appropriate calibre of the flowmeter.
