MAO Flow Meters Sales Deck 2012

2 | Presentation Title What is the MAO Flow Meter? The MAO flow meter is an instrument used for monitoring or measuring the flow rate of a liquid. What type of Flow Meter does ChemTec manufacturer? No rotating internals Handles corrosive & non-corrosive liquids Works best with liquids of 150 cps viscosity or less No bearings Single moving part In-line metering Output: Analog, Digital, Current loop Measures low flows ChemTec manufactures a unique flow meter called the MAO; consist of a single moving part.

3 | Presentation Title How does it work? ChemTecs flow meters measure the volumetric flow of liquids in pipes Fluid flows through the unit and displaces the Teflon ® encapsulated piston. The displacement is proportional to the volumetric flow through the unit. A transducer (encapsulated in the body, outside of the fluid path) senses the displacement of the piston. The transducers signal is converted by a microprocessor-based conditioning circuit then sends the signal to 3 types of outputs: volt, pulse and current loop. 3 types of outputs Analog: 0-5 VDC (Min. load impedance- 5k ohm in parallel with 250pf) Digital: 200 Hz (Square wave 50% duty cycle, TTL compatible output) Current Loop: 4-20 mA (Loop load- 100=1% ¼ watt) Flow in Flow out

6 | Presentation Title Where is the MAO used? Wet benches Cooling systems Materials consumption measurement Process controls Chemical processing of raw/caustic material Portable and permanent chemical injection skids Chemical dosing, mixing, delivery systems Chemical feed systems Pharmaceutical processing equipment used in dosing, spraying, dispensing of pharmaceutical grade material Beverage dispensing, mixing, processing

7 | Presentation Title Selecting the correct MAO for your customer Choosing the correct flow meter is important. Have a clear understanding of the application in which it will be used. Particularly the process fluid and installation requirements of the application. What is being measured? Is the fluid clean? Display or electronic signal output? Range? Min/max flow rate for flow meter Min/max process temperature Is the fluid chemically compatible with the flow meter wetted parts? Pipe size? Fittings? Installation? Direction? Consider the piping (what direction) and location of the flow meter. Is there magnetic fields present or possible?

8 | Presentation Title Installation Purge all lines of air before use Placement In-line before control valves Should not drain completely when flow ceases 10 microns filter installed ahead of the flow meter Do not place near ferrous material or strong electro- magnetic fields Sensitive to velocity profile disturbances in the flow stream Straight lengths of 10 inside diameters upstream & 5 inside diameters downstream Do not use pipe paste. Teflon tape can shred and enter MAO flow stream
