Coriolis mass flow meter/controller

PLV-NF40 series Coriolis mass flow meter/controller

Product Introduction

The Coriolis mass flowmeter is highly praised for its measurement accuracy and characteristics that are not affected by fluid characteristics.

PLV40FE applies this technology to very low flow measurements and integrates PID controllers and batch functions internally to achieve flow control or quantitative feeding.

1、 Product Overview

◆ Direct measurement of mass flow rate

◆ Precision can reach ± 0.5% F.S for gases and ± 0.25% F.S for liquids

◆ No dead zones

◆ Fast response and adjustment speed

◆ High precision and good repeatability

Integrated PID controller to regulate flow rate

◆ High cost-effectiveness

◆ High reliability and long service life

◆ No thermal drift, negligible temperature and time drift

◆ Can simultaneously output fluid density and temperature

◆ High viscosity fluids and high-density gases can be measured

◆ Not significantly affected by environmental vibrations

The Coriolis mass flow controller is highly praised for its measurement accuracy and characteristics that are not affected by fluid characteristics.

PLV40FE contains a uniquely shaped single loop sensor that forms part of the oscillation system.

When the fluid flows through the sensor circuit, the Coriolis force causes a variable phase shift, which is detected by the sensor and transmitted to the DSP processor on the integrated circuit board for processing.

The output signal generated by the variable phase shift is strictly proportional to the actual mass flow rate,

Even under changes in working conditions such as pressure, temperature, density, conductivity, and viscosity, unparalleled ultra-high performance can be achieved.

PLV40FE-X simultaneously measures mass flow rate, fluid density, and temperature and outputs two levels of accuracy: ± 0.25% for liquid measurement or ± 0.5% for gas measurement.

Capable of meeting the needs of most customers, it can be applied to various laboratory experiments as well as complex industrial environments.
