1、Overview:
Walsn’s US Series Coriolis mass flow meters use a classic U-shape for their flowtubes. The Walsn mass flow meter is equipped with a transmitter utilizing a digital signal processor (DSP), integrated with digital closed-loop vibration control (DLC), which performs calculations and monitors diagnostic functions of the sensor. This provides high accuracy measurement, wide range ability and excellent reliability for you. Online node-configuration, diagnostics and data recording can be handled directly through a Hart communicator or Modbus.
Walsn’s US Series flowmeter not only provides mass flow rate, but can also calculate: density, temperature volumetric flow rate, total flow and component fractions online and in real-time
2、Features:
◆ U shape design – provides excellent stability and repeatability
◆ Dedicated ASIC with digital closed-loop control (DLC) improves the performance of gas-liquid flow measurement
◆ Dynamic vibration balance (DVB) technology enhances system stability
◆ 2-point temperature compensation and process pressure compensation
◆ Special configurations for difficult applications (e.g. high temperature)
