Comate VFM60 is a powerful flow meter utilizing “Karman vortex” theory, which can meet the requirement of measuring the flow rate of various fluids such as gas, steam and liquid. The product has an excellent signal processing capability, with lower measuring limit, better stability and accuracy. The digital transmitter support communication via bluetooth and APP which allows users to access and diagnose the meter remotely, on a smart device. The unique dual-sensor design and special signal processing method eliminates vibration signals to provide a reliable performance. The VFM60 series is a highly customisable product, allowing upgrades and customisation according to specific requirements.
Process fluids: Liquid, natural gas, biogas, saturated steam, superheated steam applications, etc. Fluids must be homogeneous and single-phase.
Measurable parameter:
Standard version: Volume flow rate in pipe, velocity (Can measure mass flow rate, temperature and pressure if wired to separate RTD and pressure transmitter.)
Multi-variable version: Mass flow rate, volume flow rate in standard condition, temperature, pressure, volume flow rate in pipe, velocity.
