Product catalog summary
Overview: The document provides detailed information about the Malema M-10001 Series Rotary Flow Meters, focusing on their specifications, features, applications, and installation guidelines.
Specifications: The M-10001 Series flow meters are designed for low flow sensitivity and high reliability. They offer multiple output options including 4-20 mA, 0-10 VDC, or pulse output. The flow meters are span-adjustable over the flow range and are suitable for liquids only. The accuracy is 5% full scale with a repeatability of 1% and set point hysteresis of 6%.
Features: Key features include state-of-the-art electronics, adjustable flow switch, small footprint, and availability in all-PTFE models (except sapphire shaft). The flow meters are suitable for applications such as sample lines, chemical injection, semiconductor tools, and wet process systems.
Materials and Construction: The flow meters are available in materials like PTFE and 316 Stainless Steel, with other materials available upon request. Special versions for high pressure and extreme temperatures are also available.
Operation: The rotational velocity of the rotary wheel is linearly proportional to the fluid's average velocity. A Hall Effect sensor generates a square wave pulse from magnets in the rotor wheel. The output can be directly relayed or converted to voltage or current outputs.
Installation and Maintenance: The M-10001 unit should be installed horizontally with the rotor axis perpendicular to the ground. It is easily disassembled for cleaning. Special configurations may incur additional costs.
Certifications: The M-10001 with voltage and pulse outputs complies with CE directives for immunity and product safety.
Linearization: Linearizers improve the linearity of the output signal, compensating for frequency offset characteristics. This feature is standard on units with voltage output.
Ordering Information: The document provides contact details for custom versions and special requirements, emphasizing Malema's capability to tailor solutions to customer needs.

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 equal...
