Macnaught Pulse Oil Meter - 1/2" IM012P-01
Available
The Macnaught IM012P-01 is an in-line oil meter with pulse output only. It has no display. It sends a pulse signal for every small amount of oil that passes, and other equipment counts those pulses. It is an in-line oval gear meter with pulse output only, designed to measure lubricating oils, and includes a 1m fly lead for connecting it to other devices. An oval gear meter works by the fluid turning two oval gears, and the register counts the turns.
It has 1/2" BSP(F) inlet and outlet ports and a flow range of 1 to 30 L/min. Accuracy is around +/- 0.5% of reading and the maximum pressure is 6,900 kPa (1,000 psi). It suits oils up to SAE 140. Before use, confirm the fluid is compatible with the meter. Choose a pulse meter when the counting is done by a separate system. Choose the electronic meter (IM012E-01) if you want a display on the meter itself. The IM019P-01 is the 3/4" pulse version for higher flows.
