Elster 20 with Reed Switch

This Elster AMCO Water line of high precision oscillating piston oil flow meters covers a range of flows from 2.6 to 800 GPH. These meters are capable of handling a wide viscosity range including light and medium heating oil, diesel, and even heavy heating oil (meters 3/4” and 1”). Accuracy is ±1% throughout the operating flow range for each meter. Each meter is tested with #2 oil at 70°F to verify the accuracy.
