Impulse Swirl Meter with Port Flow Rig and Display .
Impulse Swirl Meter with Port Flow Rig and Display
- Swirl meter comprises a Honeycomb matrix mounted within cylindrical housing.
- The dimensions of individual cell of the matrix being suitable for arresting the swirl of the incoming air
matrix is connected via a torque to a strain gauge transducer which is
calibrated by suspending weights over pulleys either side of the torque
- A low
range strain gauge transducer measures the positive or negative force
caused by the torque reaction produced when swirling air is straightened
by the honeycomb. This torque is normally calibrated over a small range
for higher accuracy.
length of torque arm is such as to enable torque values up to 0.1Nm to

direction and is supplied complete with adaptor plate having a pilot
bore of diameter 50mm.
- The display unit contains the signal conditioning electronics in a rack mounting module.

variable speed centrifugal fan/blower unit, capable of 100mBar static
pressure and a flow rate of 300m/hr, is attached to a base plate on the
bottom level of the frame. It is used for blowing or drawing air through
the cylinder head port model. The mode of control may either be direct
fan speed set point or by the test piece pressure drop set point.
- Intended for use with port models with a nominal free air capacity of 50 litres/second.
