| M Series Digital / Analog Mass Flow Meters |
| Manufacturer: Alicat Scientific |

|
Digital or analog mass flow meters, regardless of manufacturer, serve a single purpose...to measure the flow of gases through a system. Mass flow meters must be accurate, versatile, dependable and cost effective.
The Alicat Scientific's M series digital / analog mass flow meter was designed to meet and exceed the requirements that customers place on mass flow meters:
Simplicity
Alicat M series mass flow meters were designed to be used as a stand-alone device. With the native display, a user can easily change the configuration of the meter without the need for computers, complicated software or scripts.
Accuracy
Alicat M series mass flow meters can be configured with an accuracy spec of up to +/-(0.4% of reading + 0.2% of full scale) with a high-accuracy calibration. Standard calibrations are rated at +/-(0.8% of reading + 0.2% of full scale)
Reduced Cost of Ownership
Alicat M series and V series flow meters require very little power to run thereby reducing operating costs. M and V series flow instruments also have less pressure drop when compared to similar flow devices. Reduced pressure drop means more process fluids go into your process and not into your measurement devices. The M series mass flow meters also measure pressure, temperature and volumetric flow in addition to mass flow which means fewer instruments you will have to buy and install. Adding a totalizer allows users to see how much media has flowed through the system, making it a great way to monitor usage and identify waste.
Versatility
M series mass flow meters are available in any flow range from 0.5SCCM through 1500SLPM. They are equipped with multiple analog outputs in addition to the RS-232 digital output. The M series meter can also be equipped with an Alicat 9V battery pack to make a stand alone secondary calibration standard or flow verification meter.
Speed
With a response time of under 10 milliseconds, Alicat mass flow meters respond more than twice as fast as your eye can blink.
Small Size
The M series mass flow meter has a footprint of 2.37'X1.050' through 4.00'X1.60' making it easy to integrate into systems or to use as a stand-alone calibrator.
Repeatability
Alicat's patented technology allows its mass flow meters to have very few moving parts. All of the internal components are fixed in place resulting in very little physical change inside the mass flow meter. Little physical change in the flow cavity means higher rates of consistency and repeatability. Alicat M series mass flow meters have a repeatability of +/-0.2% of FS
Dependability
There are currently over 22,000 Alicat products in service around the world. Alicat mass flow meters are being used in processes like leak detection, flow monitoring and atmospheric testing.
All Alicat Scientific mass flow meter calibrations are NIST traceable.
