Macnaught M Series Mechanical Flow Meter Macnaught M Series Mechanical Register Flow Meters are Non-Powered Industrial Grade Mechanical Display totalizing flow devices. Well suited for registering totals in most fluid applications. Designed for clean process fluid, this meter is not for measuring air or liquids laden with solids. This Macnaught meter class has decades of industrial experience with thousands in service, many operating in perfect condition for over 30 years. ALL M SERIES MECHANICAL METERS PROVIDE A STANDARD 1% ACCURACY with .03% Repeatability of Flow. ½”, 1”, 1,5” and 2” stocked sizes Designed for Precise Volumetric Clean Process Fluid Totalizing Measurement No Flow Conditioning – put the meter where you need it Large Stock of Meter and Display Inventory including Hazard Classification Meters Immediate response to Flow Meter Inquires Receive an Immediate Flow Meter Proposal or Call our Meter Hotline - (813) 896-2710 METER RFQ FORM Fluid Categories Well Suited for MX Oval Gear Flow Meters Fuels • Oils • Solvents • DEF/ADBLUE • Greases • Lubricants • Fuel Additives • Glycols Polyols • Isocyanates • Asphalt Emulsions • Sealers • Epoxies • Adhesives • DI Water General Water • Acids • Bases • Inks • Chemical Additives • All Clean Process Fluids Flow Totalizing Applications Well Suited for Macnaught Oval Gear Flow Meters Bio Diesel Blending &Production Lubricant Blending &Dispensing Glycols ProcessMeasurement Diesel Fuel AdditiveBlending Hydraulic FluidMeasurement Sealants & AdhesiveManufacturing Fuel MeasurementBasic Test Stands Epoxy / Glue Production Fuel MeasurementAdvanced Polyurethane FoamRatio Blending Polymer Production &Measurement Ethanol Blends Agriculture ChemicalBlending & Dispensing High ViscosityFluid Measurement Heating OilMeasurement Ink Blending DI and General WaterLoop Measurement Boiler FuelMeasurement Solvent Manufacturing,Blending, Dispensing Additive Injection &Blending Bunker & VesselFuel Measurement Paint & CoatingManufacturing Acids & BasesMeasurement Receive an Immediate Flow Meter Proposal or Call our Meter Hotline - (813) 896-2710 METER RFQ FORM Principle of Operation Principle of Operation The measuring element of an oval gear meter consists of two high-precision splined oval-shaped gears (Rotors). The gears are driven by the flow of the media and “mesh” together. In the presence of flow, exact known defined volumes of fluid are swept through the meter per each rotor rotation. As flow increases, so does the rotational speed of the Rotors. The number of revolutions is a precise highly accurate measure of the fluid that has passed through the meter. Regardless of viscosity, pressure, or temperature. Each “active” Rotor rotation creates a pulse and is detected by a sensor. Each meter is individually calibrated per ISO 17025 standards to .1% accuracy METER FLOW Mech Quick Specs Mechanical Meter Quick Specs Macnaught Mechanical Flow Meters and Displays.
