Model Selection
The flowmeter model selection is very important in application of instrument. The related information shows that in practical application of instrument, 2/3 failures are caused by incorrect selection of model and incorrect installation of instrument to which the special attention shall be paid.
1. Technological data collection
a. The measured fluid name and its chemical substances
b. Maximum flux, minimum flux and normal flux
c. Maximum working pressure;
d. Maximum temperature, minimum temperature.
2. The measured liquid shall have certain conductivity, electrical conductivity ≥5μS/cm.
3. The maximum flux and the minimum flux shall meet the values in the measurable flux range table.
4. The actual maximum working pressure shall be less than the rated working pressure of flowmeter.
5. The maximum working temperature and the minimum working temperature shall meet the temperature requirements stipulated for flowmeter.
6. Whether negative pressure exists or not in the processing pipeline shall be confirmed.

You can also select the appropriate flowmeter electromagnetic flowmeter according to actual use, and if the interior diameter of the electromagnetic flowmeter selected differs from that of the existing process pipe, then pipe reduction or expansion shall be considered.

1. If the pipeline should be contracted, whether the pressure loss caused by the pipe contraction will affect the process flow or not shall be considered.
2. Considering the measurement accuracy and price, you can choose a smaller diameter electromagnetic flowmeter, which can reduce the investment relatively.
3. When measuring clean water, the economic velocity is 2m/s ~3m/s; when measuring the solution of crystallization, the velocity shall be increased approximately to common velocity of ≥2 m/s ,in order to prevent the electrode of electromagnetic from flowmeter being covered.
