Gear Flowmeter for High Pressure High Viscosity and Micro Flow Measurement

High pressure resistance (1.0–40 MPa)
High and low temperature resistance (–40°C to 150°C)
Can measure various viscous media
High accuracy and high repeatability
Pulse output / analog output optional
Wide turndown ratio (up to 1:100)
Wide measuring range
Strong corrosion and contamination resistance (acids and alkalis)

The LW series gear flow meter is equipped with a pulse transmitter and a digital LCD display unit. It provides stable and accurate pulse signal output, and can also directly display instantaneous and cumulative flow rates on site. It offers various remote signal transmission functions. When used with electronic display instruments, it enables centralized remote control of totalization, batching, and instantaneous flow measurement. In addition, it is capable of measuring high-temperature and high-viscosity liquids. Its excellent performance allows it to adapt well to a wide range of complex operating conditions.
