GENERAL DESCRIPTION:
The OMP Flowmeter combines high accuracy, repeatability and low cost with a variety of material combinations allowing it to solve just about any flow metering problem. The OMP series positive displacement flowmeters use an oval gear design to accurately meter the flow of viscous liquids. The oval gear design provides highly precise measurements with a lower pressure drop relative to other types of gear type meters. The OMP low flow series are available with ryton bodies for lower pressure applications and stainless steel bodies for pressures up to 8000 PSIG. The standard gear design can measure fluids with viscosities up to 1000 centipoise with special gear designs available for high viscosities. A pulse output is provided for input to a variety of display, batch control or distributed control systems.
