Positive Displacement Meters
LSZ Series Double-Rotator Flowmeter (Also called Bi-Rotor Flowmeter) is a new kind of positive displacement flowmeter developed specifically to serve as the heart in loading facilities at oil product depots. Contained in the measuring chamber is a pair of rotators having special spiral gear teeth, the design of which is responsible for successfully eliminating pulsation in the flow stream. The special sand proof and self-lubricating design can measure sand content and high water content in oil. This type of flowmeter has many advantages such as high-precision, high security, smooth running, low noise and a long life span.
