Description

ValuMass Series 540 Thermal Mass Insertion Flow Meters

ValuMass leads the market in offering effective, reliable solutions for measuring the mass of air and gas. With our ValuMass Series 540 Thermal Mass Insertion Flow Meters, your temperature-sensitive applications are in good hands. These carefully engineered instruments offer precise measurement of both hot and cold gas streams. They have been designed with a sort of “battle-proof” construction, ensuring long-term accuracy under the harshest conditions.

The ValuMass Series 540 is designed for industries that demand top-quality, reliable gas flow rate control and monitoring. These thermal mass insertion flow meters go to the heart of the application. They provide unparalleled service at a price that creates real value for the end user.

  • Meter Type: Insertion – ideal for retrofit and new applications.
  • Enclosure: Completely integrated electronics promote durability and user-friendliness.
  • Warranty: Ranging from 1 to 4 years, assuring reliability and performance.
  • Certifications: CE marked, attesting to its quality and compliance with European standards.
  • Build and Design: Incorporating reference-grade platinum and other high-quality materials, these flow meters are crafted for longevity and resistance to corrosion and abrasion.

Our ValuMass Series 540 is an indispensable tool for operators needing an accurate measure of mass flow in various gas and air applications. Built to provide sustained performance, these meters offer:

  • A rugged, cleaned, and easily maintainable sensor.
  • Temperature compensation to counterbalance any ambient temperature fluctuations.
  • Designed for easy insertion with available lengths ranging from 6” to 60”.
  • Advanced RTD technology guarantees consistent and precise measurements.
