The BOWMONK AFM2 is a compact, portable electronic instrument for measuring and recording the maximum deceleration possible on a airport runway or road surface.

The BOWMONK AFM2 is the modern day equivalent of a mechanical decelerometer such as the Bowmonk Brakemeter or Tapley Brake Meter.

It contains a solid state accelerometer and an accurate crystal controlled clock. During a friction test, the accelerometer measures the deceleration (g-force) experienced by the transporting vehicle, 400 times per second with an accuracy of better then 2%. The output is read by a microprocessor and stored in the 128K byte memory for automatic analysis at the end of the test.


	Records true vehicle deceleration Provides hard copy printouts of up to 99 friction tests together with calculated total runway average or thirds. Compensates for peaking due to initial vehicle pitching. Indicates friction values 10% below average and disregards tests cancelled by operator or considered faulty. Permits selection of airport, runway and operator through keypad or barcodes. No mounting kit or connections to the vehicle are required Can be used with enabled ABS braking systems

In use the BOWMONK AFM2 is simply positioned on the passenger seat or in the footwell of the vehicle- usually a good condition pick-up with balanced springing and good tires. The vehicle does not need to come to a complete stop to calculate runway friction.

Control and setting of the BOWMONK AFM2 is via a seven button keypad which provides for airport, runway and operator identification.

The BOWMONK AFM2 is fitted with a two line alpha-numeric liquid crystal display. This is used to prompt the user for command entry via the keypad, to indicate results and to give any error messages. Night time operation is facilitated by back-lighting of the display panel.

The BOWMONK AFM2 contains a miniature dot matrix impact printer capable of printing text in 40 columns and graphics of 240 dots per line. Printout of results is obtained by pressing the (P) in the memory and the printout will show individual friction readings, averages for each one third of the runway and a total average of all friction readings taken. The printout will not fade and duplicate copies can be taken automatically.

The BOWMONK AFM2 is powered by an internal rechargeable battery. When fully charged this will power the instrument for at least 12 hours testing and printing. The battery voltage and charge can be shown on the display.
