VALVE-TRONIC PlusTM
 Electronic Flow Controller

Description

The VALVE-TRONIC Plus™ is designed for use in highly demanding industrial applications that require accurate flow control and measurement. It can function as a stand-alone controller for basic applications or become an integral part of a process control system for automatic flow control. The Valve-Tronic Plus™ is available with optional Temperature / Pressure compensation for real-time flow correction, providing the most accurate flow measurement possible.

Features

  • Large LCD display provides vital information such as actual flow rate, totalized flow, valve position, alarms, and diagnostic messages

  • Simple and intuitive programming menus

  • Field programmable engineering units

  • Waukee’s new magnetic sensor technology immune to problems related with dirty oil

  • Configurable to control based on rate of flow or valve position for applications where the Process Variable (PV) is Dew-point, Carbon Potential, etc.

  • Standard Modbus TCP for easy integration with control systems

  • Optional Temperature / Pressure compensation for added accuracy

  • Manual actuation of value possible

  • Easy to install

  • Ideal for customers who need to control and data log flow rates for compliance to NADCAP, AMS2750D, or CQI 9

  • Field calibration for null and span

  • Advanced polynomial calibration for high accuracy over the entire range of the meter

  • Built-in Web Server with remote access to device

  • Full PID setpoint control

  • Calibration in state-of-art ISO/IEC 17025:2005 accredited laboratory
