The VRSE volume flow controller is a low-cost alternative to the VRME volume flow controller model. The volume flow controller serves the pressure independent control of variable volume flows in supply and exhaust air systems. The volume flow controller consists of a regulating flap, which can also serve simultaneously as a shut-off damper, and two measuring sticks for volume flow measurement incorporated in the tube body as well as the electronic controller components.

  • Air speeds of 1.4 to 12.0 m/s
  • Air leakage flow at closed regulating flap according to EN 1751 Class 4
  • Housing leakage according to EN 1751 Class C

Product information:
The differential pressure measurement is performed by means of measuring sticks on which 2 to 8 measuring points are attached according to the median line method.

  • Factory-set settings and programming according to volume flow required by the customer
  • The customer can adjust the set minimum and maximum flow rates subsequently
  • Push-fit ends according to DIN 12237 with double lip sealing
  • Casing and regulating flap made of galvanised sheet steel
  • Regulating flap sealing made of silicone
  • Sensor tubes made of aluminium
  • Air technical review of each unit on the test bench

Technical data:
Nominal sizes: 80 - 400 mm
Volume flow range 25 - 5400 m³/h
Volume flow control range approx. 12 - 100% of nominal volume flow
Differential pressure range 20 - 1000 PA
Ambient temperature 0 - 50 °C

Function:
The volume flows are recorded via the measuring sticks and a differential pressure sensor.
The differential pressure sensor transfers the determined speed as an electrical signal to the controller unit.
The controller unit compares this signal to the target value and adjusts the actuator accordingly.

Controller accuracy:
The controller operates from the minimum pressure difference up to the maximum pressure difference of 1000 Pa. The flow rate variation over the entire pressure range is ±10 % (up to 100 m³/h ± 10 m³/h).

Installation information:
When installing behind bends or deflections, the upstream distance must be 5 x DN. Please take also note of our document referring to the storage and installation instructions.  

Maintenance:
All components are maintenance-free, age-resistant and corrosion-proof under normal conditions. According to DIN EN 12 097, accessibility to the duct system and the volume flow controller for any adjustments or maintenance must be provided. In addition the respective manufacturer’s instructions apply to the servo motors and controllers.
