V91 rectangular Construction

• precision measuring station
  
• V91: as of 150 m³/h (1,5 m/s)
• V92: as of 36 m³/h (1.5 m/s)

• smaller installation length
• lower inherent resistance
• low noise level
• low fouling
• very little influence by unfavourable oncoming flow
• exact regulation by measuring through an average forming multiple point measuring device

Casing made of galvanised sheet steel. Flow straightener made of aluminium.

Configuration
V91: rectangular casing made galvanised sheet steel. An integrated precision air volume measuring station generates an increased differential pressure signal. On both sides with frame 22 mm option: as of 1’500 mm frame 30 mm
V92: round casing made of galvanised sheet steel. A 4-spoke-calliper guarantees measurement exactness of ±2%.

Technical Information
The measuring station can be used in the temperature range from -20 °C to +90 °C. A pneumatic or electronic transmitter can be assembled.
