Inline vortex mass flowmeter for steam, liquid, and gas applications
Spirax Sarco's VLM20 utilizes a multivariable transmitter with integral temperature and pressure sensor giving solution for the measurement needs.
Spirax Sarco's VLM20 utilizes a multivariable transmitter with integral temperature and pressure sensor giving solution for the measurement needs. A 1000 Ohm RTD and absolute pressure sensor are used to calculate density for mass flow and thermal energy flow from chilled, hot water and condensate return system. The VLM20 is precise and reliable with a steam or gas mass flow accuracy of ±1.5% of rate over a wide 30:1 flow range. Digital communications deliver real-time calculations of density, temperature, pressure, mass and thermal energy flow using Modbus RTU, BACnet MS/TP and HART communications in addition to the standard analog, pulse and relay outputs. The VLM20 is available in line sizes ½- to 12-in with flange ratings up to 600-lb. Wafer connections are also available from ½- to 4-in. Wetted material includes carbon steel and 316L stainless steel.
