DN15 stainless steel flow meter rotameter KLZZ PN6 (liquid alcohol mixture C2H5OH 96%), 11-110 l/h, 4-20mA, Ex

LZ Series Variable-area Flow-meter With Metallic Measuring Tube has the characteristics of simple construct, work rellable, widely used high precision. Convenient installing. Compared with the Variable-area Flow-meter with Glass Tube, this series has the characteristics of high-pressure proof, high-temperature proof safety, ocular reading etc. Lt can be suitable to measure the opaque medium and corrosive medium. The tube and the flange uses the material of stainless steel( 1Cr19n9Ti or 316L). The orifice, floater of normal series uses material of Stainless steel, The orifice, float and the tube lining of Anticorrosion series uses the anticorrosion material of PTEF(Teflon). LZ Series Flow-meter With Metallic Measuring Tube is the VarіabІe-area Flow-meter.As the fluid flow upwards in the metal tube, the floater moves upwards to a certain position where the lift force and the gravitational force meets balance,at the moment,the circulation area between the float and the orifice(or the cone tube) keeps fixed. The circulation area is in proportion to the height of the floater, it means the height of the floater represent the volume of the flow. When the floater moves up and down, it transmit its position to the indicator outside in the form of Magnetic-coupling, in this way make the needle of the indicator moves following the movement of the floater, and by using the cam board to show the value of flow Ііnearly on the Electricity remote transmit means so far as the needle of the indicator pointed out the value, the flow-meter change the value into standard electric current signals of 4-20mA or 0-1 OmA accurately using angle displacement sensor and electric circuit.
