Types of Apex Mass Flow Meters
Standard, Aggressive and Low Pressure Drop Models
Apex Portable Mass Flowmeter
Apex Mass Flow Meter
The Apex Mass Flow Meter is standard for most applications either vacuum (limited range) or pressure. We offer for the price the most accurate and also fastest update time of any MFM on the market. Options available are numerous to customize your mass flow meter for your specific application. You can add features/options such as high calibration, totalizer function, and custom VCR gas fittings. Our on-board controller allows you to set our MFM without expensive rack mount control boxes. Using our PID parameters, you can further customize the speed and update times to better meet your application needs.
Apex Aggressive Gas Mass Flow Meter
The Apex Aggressive Gas Mass Flow Meter provides flow metering of some of the harshest applications. Gases include ammonia, butylene, chlorine, dimeth ylether, hydrogen sulfide, silane and others. The Apex Aggressive Gas Series uses alternative seals compatible with these and other aggressive/corrosive gases that normally are problematic with the standard Viton seals. Each Aggressive Gas Apex MFM comes with all inert and other gases in the library. Output connectors can be the standard NPT or welded VCR.
Apex Low Pressure Drop Mass Flow Meter
The Apex Low Pressure Drop Mass Flow Meter allows control of gas flow even where the pressure differential is low or can not be disturbed. This option can reach full-scale pressure drops as low as 0.06 PSID. When you have an application where keeping the pressure differential steady is essential or there is minimal pressure to work with, the Apex Low Pressure Drop Mass Flow Meter is the choice for you.
Apex Battery Powered Mass Flow Meter
The Apex Battery Powered MFM takes precise gas flow measurement and makes it portable through a battery pack on the unit. If you have multiple systems that need occasional measurement, need a tool for in the field gas flow measurement, or just want the ability to connect your Mass Flow Meter into multiple test ports on a system, then the Apex Battery Powered Mass Flow Meter is the perfect gas flow measurement device for you.
