VLM20

Rebranding of the Inline Flowmeter

Spirax Sarco, a leader in steam system management products and services, is excited to announce the rebranding of its VLM10 Inline Vortex Flowmeter to the new VLM20.

Mass, Volumetric, and Energy Flow Measurement for Steam, Liquid, and Gas Applications

The VLM20 is equipped with a common electronics platform that is now part of all new 20 Series Meters, ensuring improved reliability and user-friendly operation across the product range.

This advanced flowmeter integrates a SMART multivariable transmitter with built-in temperature and pressure sensors, offering users a comprehensive all-in-one solution for accurate measurement needs. A high-precision 1000 Ohm RTD and absolute pressure sensor enable the calculation of density for mass flow and thermal energy flow in applications such as chilled water, hot water, and condensate return systems.

Key Features of the VLM20:

  • Precision and Reliability: Offers a steam or gas mass flow accuracy of ± 1.5% of rate, across a wide 30:1 flow range.
  • Real-Time Calculations: Digital communications provide live density, temperature, pressure, mass, and thermal energy flow calculations using Modbus RTU, BACnet® MS/TP, and HART® communications. Standard analog, pulse, and relay outputs are also available.
  • Wide Range of Sizes and Materials: Available in line sizes ranging from ½” to 12”, with flange ratings up to 600lb ANSI. Wafer connections are available from ½” to 4”. Wetted materials include carbon steel and 316L stainless steel.

The VLM20 represents a significant upgrade in functionality and ease of use, ensuring that users benefit from accurate, real-time measurements in their steam, liquid, and gas systems.
