1 DESCRIPTIONThe Sparling /OVAL Flowmate is a postive displacementflowmeter designed for the measurement of very small flowrates in applications requiring high accuracy. It is an idealflow measurement device for various fuels like kerosene,diesel, fuel oil, etc. Units are available for remote registrationand totalization using either a reed switch or pulse simple unique construction enables the Sparling /OVAL gear meter to measure various fuels with the highest accuracyfor accountability and applications include: Fuel oil monitoring, consumption and control (kerosene,fuel oil, diesel, etc.) to engines, boilers, test stands, R & Dlabs, etc. Chemical additions in process control Lubrication oil to turbines, pumps and other equipmentSTANDARD FEATURES Sizes include1/8" and 1/4" Aluminum or SST body chambers 1% of reading accuracy or better Carbon steel, resin coated gears can apply for mostliquids Reed Switch or MR sensor for remote registration ortotalization Scaled or unscaled pulse output Metric or NPT end connections Special SST body and rotors Low pressure drop Viscosity up to 1000 cpPRINCIPLE OF OPERATIONEach meter is equipped with two OVAL shaped gears whichrotate when fluid passes through a fixed measuring of gears displaces a fixed volume of fluid.

2 The sensorpicks up gear rotation, which is proportional to fluid volumeand flow meter is designed to minimize the slippage betweengears and measuring chamber body. As a result, the OVAL gear meter is less affected due to liquid viscosity and lubricitythan other flowmeter FlowmeterTechnical SpecificationsSparling/Oval Flowmate is manufactured by Oval Corporation in SPECIFICATIONSMETER:Accuracy: 1% of readingProcess Fluid:Clean liquidMax.
