Selection Guide electromagnetic flow meter

Transmitter diameter usually used with the piping system and the same caliber. If the orbital system is to be designed, the caliber can be selected based on the flow range and flow rate. For electromagnetic flowmeter, the flow rate of 2-4m / s is more appropriate. In special cases, such as liquid with solid particles, taking into account the wear and tear, optional common flow rate ≤ 3m / s, for easily attached to the wall of the fluid flow rate can be used ≤ 2m / s, the flow rate is determined,

To determine the transmitter diameter.

Transmitter range can be based on two principles to choose: First, the instrument full scale is greater than the maximum expected maximum value of the flow, and second, the normal flow of more than 50% of the full scale to ensure a certain measurement accuracy.

2. Preliminary selection

(1) According to the learned name and nature of the measured medium to determine whether to use electromagnetic flowmeter

Note: Electromagnetic flowmeter can only measure the flow of conductive liquid, gas, oil and most organic liquid is not the case of conductive liquids

(2) According to the understanding of the nature of the medium, to determine the electrode material

Note; the company generally provides stainless steel, Hastelloy, titanium and tantalum four kinds of electrodes, the choice of which electrode should be based on the nature of the media check the relevant information manual

(2) According to the temperature of the medium to determine the use of rubber or PTFE lining (determined by the salesman)

Note: rubber temperature shall not exceed 80C;

PTFE temperature 150C, an instant resistance to 180C;

Urban sewage can generally be rubber- stainless steel electrodes

(3) According to the learned media pressure, select the form body flange specifications (determined by the salesman)

Note: The specifications of the electromagnetic flange is usually when the diameter from DN10-250, the flange rated pressure ≤1.6Mpa;

When the diameter from DN250-1000, the flange rated pressure ≤ 1.0Mpa;

When the actual medium pressure is higher than the above diameter - pressure corresponding range, for special orders, but the maximum pressure shall not exceed 6.4Mpa

(4) Determine the conductivity of the medium

Note: (1) Electromagnetic flowmeter conductivity of not less than 5uS / cm

(2) tap water conductivity of about dozens to hundreds of uS / cm, general boiler soft water (deionized water) conductive, pure water (highly distilled water) is not conductive

(3) The conductivity of gases, oils and most organic liquids is much lower than 5uS / cm and is not electrically conductive.
