McMillan Model 104 FLO-SENSORS are capable of measuring extremely low liquid flow rates from 13 mL/minute up to 10 L/minute with a full scale accuracy of ±1.0% or better!
A wide variety of fluids may be measured. Repeatable results are achieved using a patented Pelton-type microturbine wheel. This proven design has been providing precision results since 1988 and has developed a well-deserved reputation for continuous operational service for many years without failure.
Because of the compact size and economical cost of these products, the Model 104 FLO-SENSORS are suitable for a wide variety of industrial, commercial, laboratory and O.E.M. applications. Some sample applications include measurement of hydrocarbon fluids, fuels, light oils, solvents, coolant, pesticides, mild acids, alkalis, and deionized water.
Several power and output configurations are available, including both pulse and analog outputs. NIST Traceable certificates are available.
A power adapter or cable assembly is required for operation.
104 Features & Options
All models have a standard accuracy specification of ±1.0% F.S. (including linearity). An improved accuracy specification of ±0.5% F.S. is available. NIST traceable calibration certifications are standard for improved accuracy (suffix H) models and optional for standard units.
McMillan has a comprehensive range of FLO-METERS with integrated displays. A number of remote displays are also available for use with any FLO-SENSOR.
Most units have an integrated 4-pin male connector. To complete connections, either a cable assembly or power adapter should be ordered. Units where the circuit board has been epoxy potted for increased chemical resistance feature an integrated cable with pigtail leads.
Flow ranges from 13-100 mL/minute up to 1.0-10.0 L/minute are available. Consult the factory for custom requirements.
All units have compression type tube fittings as standard. Many alternate fitting types and sizes may be selected as allowed in the Product Configurator.
Most units may be specified to operate with either 12VDC or 24 VDC power. Various power adapters are also available for use with 12VDC versions.
Most units may be ordered with a 0-5VDC output or with both 0-5VDC and pulse outputs.
