OVAL Corporation products

General: High accuracy positive displacement flowmeter employing special spiral rotor to achieve low noise operation, low vibration and no-pulsation by flow.

Replacement battery pack for Oval’s Flowpet range of Flow Meters.

OME series of high accuracy, economy, helical screw, flow meters. Economical, all-round flow meter with excellent accuracy over a wide range of flows (even pulsating flow), optional temperature compensation for optimised accuracy and OMIL approval for custody transfer.

A high-performance type Coriolis flowmeter capable of directly measuring mass flow with high accuracy being equipped with a high-performance transmitter. Highly accurate measurement is possible even for the purpose of ultra micro flow measurement and short-time filling

Though limited to non-explosionproof model, CoriMate flowmeter is an easy-to-use compact Coriolis flowmeter with built-in indicator. It is a low priced flowmeter capable of metering microflow accurately.

A high-performance Coriolis flowmeter capable of directly measuring mass flowrate with high accuracy. High accurate measurement is also possible for the purpose of large mass flow measurement.

General: A high-performance Coriolis flowmeter capable of directly measuring mass flowrate with high accuracy. High accurate measurement is also possible for the purpose of large mass flow measurement.

Based on the Coriolis technologies accumulated over many years, the OVAL has broadened its current general purpose coriolis meter lineup by adding accurate, ultralow flowmetering products. The latest addition meets the expanding market needs for explosionproof products characterized by "improved performance, user friendliness, and increased operating safety."

A turbine flowmeter for industry application that allows stable high accuracy measurement for the liquid with a wide range of viscosity including low Reynolds number area. It is suited mainly for petroleum, liquefied gas, and water flowrates.

A thermistor sensor picks up the occurrence of vortex caused by the flow velocity change in the manner - changes in thermistor temperature - changes in resistance value - a train of pulses proportional to the flow velocity and measures the flowrate. Gas purge type is configured to be purged with a clean gas (room temperature) from external source to the thermistor sensor. Therefore, fluid to be measured does not touch the thermistor sensor, permitting accurate flow measurement of gases containing dust and mist, low temperature gases, or others previously thought difficult to be measured
