McMillan S Series Microturbine Liquid FLO-METERS
McMillan S Series FLO-METERS are capable of measuring extremely low liquid flow rates from 13 millilters per minute (mL/minute) up to 10 liters per minute (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 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 or many years without failure.
Because of the compact size and economical cost of these products, the S Series FLO-METERS 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, acids, alkalis, and deionized water.
Several body types are available, including both plastic and metal. NIST Traceable certificates are available on all models. A backlit LCD display is integrated into each unit and is programmed to read in mL/minute (L/minute for flow ranges 7-10).
FLOW RANGES
Flow ranges from 13-100 mL/minute up to 1.0-10.0 L/minute are available. Consult the factory for custom requirements.
POWER
Most units may be specified to operate with either 12VDC or 24VDC power. Various power adapters are also available for use with 12VDC versions.
SIGNAL INPUTS & OUTPUTS
An analog 0-5VDC output is provided on all units.
ACCURACY/LINEARITY
All models have a standard accuracy specification of ±1% F.S. (including linearity). An improved accuracy specification of ±0.5% is available. NIST traceable calibration certificates are standard for improved accuracy (“H”) models and optional for standard units.
FLUID CONNECTIONS
All units have compression type tube fittings as standard. Many alternate fitting types and sizes may be selected as noted in the Fitting Availability Codes Chart.
ELECTRICAL CONNECTIONS
Units have an integrated 4-pin male connector. To complete connections, either a cable assembly or power adapter should be ordered.
WETTED MATERIALS
The wetted materials vary depending on the model number. See the specifications for further details. Viton® O-Rings are fitted as standard.
INTEGRATED DISPLAY
A flow rate display is integrated into each unit and is programmed to read in mL/minute for ranges 3-6,
and L/minute for flow ranges 7-10.
