Xi'an LZ type metal tube

LZ metal tube variable area is the use of measuring principle for continuous measurement of volume flow in closed conduits of liquids and gases. Metal tube with a rugged and reliable, wide temperature range, high precision, low price, can be applied to measure the flow characteristics of a variety of occasions. This series of field intelligence indicating type, there is the next entry on the left and lower right out into the side installation is available. It can be widely used in liquid, gas flow measurement defense, chemical, petroleum, metallurgy, electric power, environmental protection, medicine and light industry sectors. ? LZ series of metal tube variable area flowmeter, namely in the vertical measuring tube flowmeter, when the fluid up through the tube, the float moves up one position in the lift and float float suffered gravity reach balance, circulation annulus area at this time of the float and the orifice plate (or the cone) between constant. Rise annulus area is proportional to the height of the float, the size of a highly representative of the flow of the float. When the float moves up and down, in the form of magnetic coupling will be passed to the outside position indicator, the indicator follows the float moves a pointer, and with the cam plate so that the size of the pointer indicates the linear flow rate value. Electric remote-site instruction pointer type in traffic, while another by angular displacement sensor and electrical transmission circuit, the flow rate value accurately converted into a 4-20mA
