MAO-500 flow meter: the solution for the process industry
The MAO-500 flow meter is specifically designed for heavy industrial applications. Where other meters fail due to wear or aggressive media, the MAO-500 offers maintenance-free operation thanks to its bearingless design. Because Inacom works closely with engineers in the chemical and pharmaceutical sectors, we understand that continuity is the number one priority for your installation.
Why the MAO-500 is a favourite of European engineers
In the European market, where safety and integration with PLC systems (such as Siemens or ABB) are the norm, the MAO-500 offers unique advantages:
- Direct integration: with the standard 4-20 mA output and analogue signals, you easily connect the meter to your local control system.
- Indestructible under overpressure: the meter does not fail with a sudden flow peak, which is crucial in complex pipe networks.
- Metric precision: although of American origin, we supply all calibration data and technical support in metric units (litres per minute and bar).
- Local expertise: at Inacom you get technical advice from engineers who understand the market and regulations (such as ATEX or CE).
Operation and signal processing
The MAO-500 uses a contactless measuring principle:
- Liquid displacement: the liquid flow displaces a Teflon®-encapsulated magnetic piston.
- Transducer: a transducer located outside the liquid path registers the exact position of the piston.
- Data output: a microprocessor translates this position into accurate flow data. This gives you a real-time overview of the flow in your cooling system or dosing line at all times.

Applications and installation guidelines
Thanks to its robustness, the MAO-500 flow meter is widely used in:
- Industrial cooling systems: protection and monitoring of large cooling circuits.
- Chemical dosing: accurate measurement of the consumption of (corrosive) additives.
- Process automation: feedback loop for pump controls and control valves.
- Wet benches: monitoring of process liquids in the high-tech industry.
Important for installation: for a reliable result, the meter must be mounted vertically with the inlet port facing down. It is also essential to maintain a straight pipe section of 10x the inner diameter on the inlet side to minimise turbulence. A 10 micron filter is strongly recommended to safeguard the life of the piston.
Operation and applications
The MAO-500 uses a magnetic piston that is read out contactlessly. This principle is ideal for a range of specialised industries:
- Semiconductor: ideal for ultra-precise flow monitoring in wet benches and cooling systems of chip machines.
- Petrochemicals: resistant to aggressive chemicals thanks to the all-Teflon® or 316 stainless steel version.
- Machine building: thanks to the compact design without straight inlet sections (saves space in your module).
