MPN: BB400MR Category:

The BB400MR combines three measurement ranges into one blow-by meter for an overall measurement range of 4 to 400 liters/min (LPM).  This allows the BB400MR to be used with small to large car and truck engines.  The meter’s range can be set in less than a minute by its adjustable bypass ports.  The BB400MR outputs volumetric flowrate and total volume flow information on its display, analog output, and RS-232 port.  The input and output ports can be positioned either left or right facing and the integral damping tanks have 1/4″ NPT ports for temperature and pressure probes.  In some cases, a damping tank is required upstream of the meter.  The BB400MR is DC powered and comes with an external AC/DC adapter.
