Meter specifications Repeatability: ±0.02% Linearity: ±0.15% Rangeability: 10:1 Temperature range: -40 ºF to 450ºF (-40ºC to 232ºC) standard. For higher temperature applications, consult factory. Flow ranges: Refer to the table below. Materials: Sponsler precision turbine flowmeters are constructed of 300 series stainless steel. Other materials are available to satisfy most applications. Electrical Output: A minimum of 30 mV peak to peak at the minimum repeatable flow. Pressure drop: 4 psi on water at maximum flow (typical). Actual pressure drop depends on product viscosity and flow rate. End fittings: ANSI flanges. Others available upon request. Operating pressure: Dependent on end fittings. Calibration: Sponsler precision turbine flowmeters are furnished with standard water calibration. Special calibrations available. NOTE: Meter must be calibrated in the field for the product being measured. Size Flow Range Electrical Output Pulses/Gallon (avg.

Available with Measurement Canada approvals for solvent and gasoline. b. Available with US NIST approvals for solvent, gasoline, diesel fuel, and fuel oil. c. Consult factory for ethanol approvals For flowmeter installations with less than ten pipe diameters of straight pipe upstream of the meter and five pipe diameters of straight pipe downstream of the meter (as shown below), the Liquid Controls Group recommends a flow conditioning plate. Internal flow conditioning plates are standard for 2” thru 4” flowmeters, and external flow plates are available for other sizes. Flow conditioning plates Accuracy /Performance
