Descipion

VF100 vortex street flowmeter is a precision instrument that is manufactured according to Karman vortex street principle to measure the liquid, gas and steam flow in the closed pipeline. The detecting element is sealed in the test body, and does not contact with the measured medium. No internal moving parts and no need of on-site maintenance, it is popular with users. VF100 vortex street flowmeter is widely used in the measurement management and process control of the industries such as petroleum, chemical industry, metallurgy, pharmacy, thermal power, and papermaking industry, etc.

Basic Features

　　Better vibration proof performance;

　　Lower limit flow rate is low, 1/2-1/4 of the conventional vortex street flowmeter;

　　Wide range ratio, in general, it is up to 1:30 ~1:50;

　　Simple commissioning operation, HART communication function (optional);

　　Various media measurement can be conducted combined with various vortex street sensors
