General Description
High accuracy positive displacement flowmeter for wide range of fluids including water, petroleum, solvent. The mechanical counter allows checking of total flowrates in the field. Output furnished flowmeter is also available optionally.
This oval flowmeter is suitable for viscous oils, ranging from hydraulic to light gear oils, eliminating any problems associated with changes in viscosity during operation. It also provides the advantage of positive displacement technology at a rotameter price. This flowmeter has a cost-effective design allowing for stress-free maintenance. The only wearable components are the oval gears and their axles, allowing the two-step rebuilding process to be easily accomplished in minutes with no necessary recalibration.

Structure and Operation Principle
Oval meter is generally comprised of a flow transducer and a counter mechanism. The main part of the transducer is a measuring chamber which consists of a pair of oval wheels and a sealing coupling. The counter mechanism contains speed reduction gears, adjusting device, counter, and pulse transmitter etc.

In the measuring chamber, a pair of oval wheels and cover plate makes a crescent shape cavity which is used as a measuring unit. The oval wheels are rotated by the pressure difference in the inlet and outlet of the meter and drive the inlet liquid through the cavity to the outlet, each revolution of the oval wheels displaces fluid four time the volume of the cavity, the total revolutions of the oval wheels and the revolution rate will be transferred to the mechanical counter, and the total liquid volume and instantaneous flow will be known by the pointer display and the roller integration. The attached signal generator converts the rotary axial angular shift to the pulse signal and then transmits it to the electrical indicator for remote integrated flow and instantaneous flow indication and control.
