1)  New, Digital Input/Output Options for DataMite 4  The DataMite 4 has 4 digital input channels and 2 digital output channels.  The digital inputs can be used for recording simple On/Off events, like brake light, trans brake, throttle stop, etc.  We offer convenient breakout cables and leads for you to wire in these digital signals.

One particularly useful application is the DataMite 4's Acceleration Timer, where the system will precisely time from when the trans brake is released via a digital input, and the vehicle has reached some level of acceleration, say, 0.8 Gs.  This can be very useful information for troubleshooting an inconsistent car or (heaven forbid) inconsistent driver.  We now offer the DT4-DITB Trans Brake Digital Input harness for this exact application.  It has built in signal conditioning designed for trans brake signals.

The DataMite 4 also has 2 digital output channels which can be used to turn on or off fans, lights, motors, the ignition system as an engine kill option, etc.  These can be configured by the user to "trip" on most any measured channel, most any level, either going above or below some level, and turn things On or Off for a user defined period of time.

2)  Updated DataMite Sensors and Options Web Page  We've gotten lots of feedback that the page listing all our DataMite loggers, sensors and options with pricing was very confusing.  We had to agree, and we finally got time to organize it.  Let us know what you think.

3)  New, Low Restriction Air Meter  We've developed an air meter which is lower restriction than the orifice meter we've offered in the past.  It also has more length over previous "vehicle type" meters for better flow straightening for improved consistency.  The 4" meter is part number DT4-MAFL can measure up to 800 CFM and has no small or moving parts to risk being ingested by the engine.   A 3" meter for lower flow is also available.

4)  New, Extended Swirl Blade for Small Bores  When you install very small bore adapter on our swirl meter, the meter and sensor can block a significant part of the flow area.  This makes the swirl meter a restriction and it's presence will reduce the flow readings. When installed in a 4" bore, there is almost 0 restriction from the meter.  Installed in a 2.5" bore, the swirl meter can reduce the CFM reading by 10% or more.

We have now developed a swirl blade design to extend the blade farther up into the bore.  This allows the bore adapter to enlarge below the swirl blade to increase the flow area by the swirl meter sensor and base plate, greatly reducing flow restriction.
