Mini-Wheel Flowmeter with In-line Flow
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.

The rotational velocity of the 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 embedded in the vanes of the rotor wheel. Depending on the output version of the MW-100, the pulse signal is relayed directly, converted to a 0-5 VDC (voltage) output. The voltage model is span-adjustable over the flow range of the unit.

The MTMF Series comes with or without an LCD display, and all models come with linear 0-5 V DC and 4-20 mA output. The MTMF Series measures the mass flow rate of gases in 4 ranges from 0-750 NLPM to 0-1500 NLPM as range table.

Features
Available in five flow rate ranges - capable of measuring flows from 0.2 to 20 L/min (5.2 GPM)
Cast stainless steel construction insures compatibility with a wide range of fluids for a very economical price.
Highly accurate - all MTW series flow meters provide 3% full scale linearity
Flow switch functionality - easy access filed adjustable relay to provide a single flow alarm contact closure available as an option.
Compact size - ideally suited for use in constrained spaces.

The MTHF Series comes with or without an LCD display, and all models come with linear 0-5 V DC and 4-20 mA output. The MTHF Series measures the mass flow rate of gases in 18 ranges from 0-10 NLPM to 0-50 NLPM as range table. The MTHF Series combine a mass flow transducers with an electromagnetic proportional valve. Valves are not recommended as shut of valves. Controllers us a 0-5 V DC liner set-point signal supplied from the local set-point point or from a remote source.

Many processes are damaged when exposed to too much moisture, leading to stoppages for un-scheduled maintenance, loss of product or even dangerous reactions. Correct and reliable measurement of moisture is a key part of preventative maintenance which contributes to long-term savings on energy used.
Our dew-point sensors and transmitters use ceramic impedance and polymer technologies, developed by our engineers to suit a range of applications.
