The Alicat Scientific M Series mass flow meters are an accurate, versatile, dependable and cost effective solution to measuring gas flow. Unlike traditional mass flow meters, Alicat Scientific mass flow meters utilize laminar flow and differential pressure technology which results in an extremely fast, accurate meter with no warm-up time and unparalleled versatility.
The Alicat Scientific's M Series mass flow meter was designed to meet and exceed the requirements that customers place on mass flow meters. Flow ranges are available from 0.5 standard cubic centimeters per minute to 2000 standard liters per minute with a 200:1 turndown ratio. Basic accuracy is ±0.8% of reading ±0.2% of full scale. Calibrated and ready for use with 20 gases and 10 gas blends, The M series has a remarkably fast start-up time and a response time of just 10 milliseconds.
The Alicat Scientifics M Series mass flow meter is an extremely versatile instrument. In addition to mass flow measurements, the M Series also measures pressure, temperature and volumetric flow which means fewer instruments to buy and install. 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. 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 Scientific M Series mass flow meters were designed to be used as a stand-alone device. All measured parameters are displayed in real time on the digital display. Any measured parameter can be brought to the center of the screen. The push button interface allows easy configuration of the meter without the need for computers, complicated software or scripts. The M Series features Gas Select which allows users to select from 30 gases and gas blends via the display or through the RS-232 interface. Remote displays are also available. M Series mass flow meters are equipped with multiple analog outputs in addition to the RS-232 digital output.

Here's how some of our customers used this product.
Automated Welding Gas Monitoring
The Background: Our customer is a manufacturer looking to make the use of shielding gas more efficient in their welding processes. Shielding gases are used in various types of welding to protect the weld from oxygen, nitrogen and hydrogen present in the atmosphere. Exposure to these elements can lead to weak welds and excessive splatter. Different shielding gases also play an important role in determining weld penetration profiles, arc stability, mechanical properties of the finished weld, and more.
The Problem: Delivering the right amount of shielding gas is important. Using too much wastes expensive gas while using too little fails to gain the benefits of the gas. Regulating the gases can be difficult as varying environmental conditions can affect the flow.
The Solution: The Alicat M-series is capable of metering most welding gas mixes by simply programming the gas mixture into the flow meter. No more correction factors or incorrect readings. The M-series compensates for temperature and pressure to ensure that the set-up is consistent, improving weld quality while decreasing scrap and re-work created from making multiple adjustments to the setup.
Measuring Hydrogen gas
The Background: Our customer is an industrial company conducting research into PEM electrolyzers as a major component of renewable energy storage. They require a means of measuring the hydrogen gas produced by this process.
The Problem: PEM electrolyzers are devices used to convert electricity and water into hydrogen and oxygen, these gases can then be used as a means to store energy for later use such as in hydrogen fuel cells. As this is part of a research and development project, the customer’s greatest concern is with accuracy.
The Solution: We recommended the Alicat Scientific M Series mass flow meters, an accurate, versatile, dependable and cost effective solution to measuring gas flow. The M Series is fully compensated, works well in low flow applications, and has no pressure drop making it both highly accurate and very versatile.
