Features:

1, not only can measure the general fluid flow, and can also be applied to contain various impurities such as dust, suspension, precipitation, etc.) of the fluid, such as a variety of hot gas, flue gas, natural gas, cooling circulating water, etc.

2, measuring saturated steam superheat steam can avoid stop steam condensate accumulation formation, when steam again to send, can quickly into the accurate measurement.

3, instrument ontology has a straight measuring tube, on-site installation, the installation error (such as eccentric, sealing gasket into pipe) has no effect on meter almost.

4, adopts "equalizing ring structure, when the straight pipe length is not long enough, can still be accurately measured. For example: in a 90 ° bend downstream, before the table has a length of 2 d; In a 30 ° elbow downstream, there is 0.5 D length can be in front of the table.

5, connected by "welding method", it is suitable for high temperature and high pressure fluid (e.g., superheated steam), low cost, reliable operation, stable performance.

6, adopts "jacket insulation structure, suitable for easy crystallization and easy vaporization require heating or cooling fluid (such as ammonia, some chemical products, etc.).

LWG type ring chamber orifice meter, the flow area is the center of the plate of circular hole, when the fluid through the round hole because of the sudden contraction flow speed for measuring flow, and the ring chamber orifice meter, the flow area is the outside part of the plate and the inner wall of the tube forming ring, fluid through because of the circulation area of the sudden contraction of acceleration, the fluid around the edges of the ring chamber orifice plate boundary layer is cylindrical, which occurs when the fluid resistance on the similar principle, so the ring chamber orifice meter so close to a fluid resistance coefficient, which makes the two possible with similar coefficient of outflow.
