LSZ Double Rotator Flowmeter:

LSZ Double Rotator (PD) Flow Meter is an advanced volumetric measurement flow meter. It is a precise instrument designed to measure liquid flow in the pipeline, with features of high measurement precision, smooth running, no pulsation, low noise, long service life and excellent adaptability to various viscosities. It is widely used in various fields such as petroleum, chemical, metallurgy, power, shipbuilding, and food industries etc. It is especially suitable for custody transfer measurement for crude oil, high condensed oil, crude oil with water, petroleum products, as well as measuring management and engineering control automations.
