Variable journey ke shi mass flow meter that does all can

The utility model belongs to the technical field of automatic?measurement, particularly, a variable journey ke shi mass flow meter that does all can has been disclosed. Variable journey ke shi mass flow meter that does all can is including surveying buret, electromagnetic signal detector, driver, it distributed in the cross -section of tubular shunt ring week to survey buret and shunt tubes. The figure of shunt tubes can be one or more, is symmetry or asymmetric in form, satisfies with under the equal pressure, flows past the flow unanimity of surveying buret and shunt tubes. The utility model discloses the variable journey ke shi that discloses power flowmeter can not satisfy the measurement down of the different flows of user under the condition of undergauge the user, and ultra -large diameter 's mass flow can be surveyed to flowmeter small -bore relatively the while. Structural mounting dimension is little, the installation of being convenient for, and cost of transportation and material?cost have been sa
