Macnaught Mechanical Diesel Meter AMFM

The Macnaught AMFM is a mechanical diesel meter. It counts the diesel you pump with no power or batteries, so it suits remote field use and in-line use. It uses a nutating disc measuring mechanism, the same idea as many water meters, and reads 20 to 120 L/min with +/-1% accuracy.

It has a 4-digit resettable batch total and a non-resettable accumulative total, and the register rotates through 180 degrees so you can read it from the side. It has 1" BSP female inlet and outlet and a maximum pressure of 3.5 bar (50 psi). You can fine tune it in the field with a calibration screw. Choose the AMFM if you want a battery-free meter for higher flows. Choose the ADTFM if you want electronic totals and a stock alarm.
