LPS Scraper Flow Meter

Introduction and applications

The LPS scraper flow meter is a positive-displacement flow meter developed on the basis of advanced foreign technology. It offers high flow capacity, low noise, high accuracy, good repeatability, wide turndown, light weight and long service life. The meter consists of a measuring transmitter, a large-digit counter, an instantaneous rate indicator and a splitter: the resettable large-digit counter shows the volume that has passed through the meter, the rate indicator shows the instantaneous flow, and an optional transmitter provides remote output of the flow signal.

At a 20:1 turndown the LPS meter achieves ±0.2% accuracy with ±0.03% repeatability; at 40:1 it achieves ±0.35% accuracy with ±0.06% repeatability. Typical uses include fast refuelling of vehicles, ships and aircraft, tanker-truck and ship loading and unloading, pipeline metering, custody-transfer measurement, and process control in refineries and petrochemical plants. It can also serve as a master meter for calibrating other positive-displacement meters.
