Blow-by meter covers most engine test applications


The M400MR engine blow-by meter is suitable for diesel and spark-ignition (gasoline) engines of almost any capacity, and the built-in signal conditioning enables it to operate in either flowmeter or totaliser mode. Users can select from three flow ranges by means of bypass ports, giving a total measurement range of 4-400 LPM.

Accuracy is +/-1% of reading and repeatability is +/-0.5% of reading. Total flow can be monitored in programmable amounts up to 1000 litres per time.

Compact, accurate and reliable, the blow-by meter is equally useful for engine dynamometers and in-vehicle testing.

Typical applications range from engine development and lubricant testing to fleet maintenance.

As standard the blow-by meter is supplied with an analogue output, but Labcell offers an optional CAN interface for simpler integration within data acquisition systems.

In addition, it has an integral LED display for indicating the operating mode and flow in a choice of engineering units (LPM, CFM, litres and cubic feet).

Because the solid-state meter utilises the vortex-shedding principle for flow measurement, it benefits from a fast response, perfect zero stability, very low flow restriction, and insensitivity to temperature, pressure and velocity.

There are no moving parts, so it is robust, reliable and virtually maintenance-free.

Each M400MR features integral chambers to minimise the affects of pulsations and carry over.

Connection to the engine valve cover is made via a 20mm (0.75in.) hose, and ports are provided for temperature and pressure probes (if required), making installation very straightforward.

All M400MR blow-by meters are delivered pre-calibrated and Labcell offers full support and ongoing calibration services to suit customers’ audit and ISO requirements, with very rapid turnaround times.
