Introducing the HBM453 Flow Meter

J-TEC Associates HBM453 Blow-by flow meter.fw

J-TEC’s HBM453 Flow Meter provides an indication of piston-ring leakage under actual operating conditions by measuring the flow out of the crankcase vent or sump vent.

Discover power lost to problems with ring flutter, ring end gap, cylinder wall distortion, ring clearance and ring tension.

J-TEC’s HBM453 Flow Meter provides all the advantages of vortex shedding flow meters, in a design that is perfect for repair shops, weekend racers and auto enthusiasts.

Our vortex shedding technology produces flow meters with low pressure drop and high turndown ratio, which makes them ideal for measurement of engine air intake, crankcase blow-by and exhaust flows.

The patented J-TEC design provides high accuracy and repeatability over an extended flow range. Because the meters have no moving parts, they are rugged and virtually trouble-free.

The HBM453 Hand-Held Blow-By Flow Meter is designed for easy use in the field for engine testing.

This system comes complete with an In- Line Flow Meter and a digital read-out unit.

The read-out unit supplies power for the HBM453 Flow Meter, as well as providing a visual read-out of the flow measured.

If the health of your engine is important to you, the J-TEC HBM453 Hand-Held Blow-By Flow Meter System is the answer for on-the-spot testing of piston ring blow-by and an early alert of engine wear problems.
