Thermal mass flow meters and flow switches from…

Welcome to Eldridge Products, Inc. (EPI), the premier thermal mass flowmeter manufacturer in the world. Our company produces a wide offering of thermal mass flowmeters for gas flow meter measurement and gas flow control. EPI, founded in 1988, has been an industry leader for over 25 years, specializing in manufacturing thermal mass flowmeters and other flowmeter related technology.

For a complete, printable overview of our products, download our new EPI color brochure or take a look at a .pdf version of our slide presentation.

EPI produces the Master-Touch™ and ValuMass™ brands of thermal mass flow meters and thermal mass flow switches. Trademarked brands for these thermal mass flow meter products include EPI™, Master-Touch™, EPICom™, FAT™, E-Logger™, LightWIRE™, ValuMass™

EPI’s state-of-the-art thermal mass flow sensors can detect mass flow rates, from very low to very high mass flow velocities, with an unparalleled level of accuracy.  Our experienced staff and engineers are helping many organizations use this thermal mass flow meter technology to go “Green”, by successfully tracking and managing their gas usage, in order to reduce their energy costs.

Our advanced thermal mass flowmeter technology is robust and easy-to-use. These thermal mass flowmeter products allow you to capture instantaneous gas mass flow rate and elapsed mass flow total. We offer a variety of thermal mass flowmeters to suit most applications requiring process gas flow measurement and process flow control. Good gas flowmeter data can help you reduce operating costs and/or achieve compliance with regulatory requirements. Although EPI has various standardized thermal mass flowmeter product configurations, your thermal mass flowmeter is hand-assembled and calibrated at the factory to meet your actual process conditions, specifications and requirements.

Our patented thermal mass Flow Averaging Tubes (FAT™) provide accurate flow meter measurements in large pipes, ducts and exhaust stacks. These FAT thermal flow meters work well in applications with very limited straight runs and are well suited for facility upgrades, retrofits, expansions and general modernization.

Various Notified Body certifications, such as CE, CSA/CUS & ATEX are available for EPI’s thermal mass flowmeter product line. Please refer to product specifications and data sheets on this web site.

To discover how we can assist you and your company with current and future thermal mass flowmeter needs, please select an option from the menu on the left.  Our Sales and Customer Support staff are available to answer all of your flowmeter purchasing, implementing, and calibration questions via e-mail or telephone Monday through Friday, 8am to 5pm Pacific Standard Time.  We appreciate your taking the time to visit our site and hope we can apply one of flowmeters to your application and do business with you soon.

Thank you, from the EPI Thermal Mass Flowmeter products team.
