Rotary Flow Meter flow meter and switch with right-angle flow Very low flow sensitivity State-of-the-art electronics - high reliability Adjustable flow switch - built in Small foot print All-PTFE models available (except sapphire Tangential turbine flow meters continue to be the most common way to measure flow electronically in a wide range of industries. Enhancements to tangential turbine flow meter systems are producing a flow-sensing device that is smaller, easier to install, and more accurate than ever before. Malema manufactures a line of Tangential Turbine (also called Paddle Wheel) Flow meters that utilize sophisticated circuitry to foster signal conditioning. Sample lines Chemical injection Semiconductor tools ELEC- HOUSING Model with 1/4" ports. rotary wheel varies linearly with the average velocity of the fluid flowing through the flow meter. A square wave pulse is generated by a Hall Effect from magnets rotor wheel. Depending on relayed directly, converted to a 0-10 VDC (voltage) output or a 4-20 mA (current) output. The voltage and current models are span-adjustable over the flow range of the unit. Custom Versions Available Malema welcomes the opportunity to apply its flow sensor experience to work for its customers. Please contact the factory for any special requirements; such as ports, extreme temperature Calibration Range Accuracy: 5% Full Scale Material Versions Other materials available on request.

Linearizers are electronic devices that improve the linearity of the output signal of turbine flow meters. The output frequency is essentially a straight-line frequency as a function of flow rate which does not pass through zero. Left uncorrected, this will result in a K-factor which varies with the flow rate. Simple, low-cost linearizers will compensate and correct for the frequency offset characteristics. These linearizers use a method of offset frequency injection to compensate the frequency characteristics. Offset frequency injection is implemented electronically by adding a signal...

Rotary Flow Meter The standard M-l 0001 unit must be installed horizontally with the axis of the rotor perpendicular to the ground (axis facing the sky).. If necessary the flow meter is easily disassembled and cleaned. For detailed directions, please refer to our "Installation and Maintenance" sheet. Standard Component Materials * Special Material Notes: ■ The M-l 0001 is available with special flare-fittings, please contact factory ■ Shaft: Sapphire shaft is available for acid applications ■ Window: Any of the materials are available ■ O-Ring: Polyimide, Buna, and other elastomers are...
