Inline vortex mass flowmeter
The VLM20 inline vortex mass flowmeter that measures mass, volumetric, and energy flow measurement for steam, liquid, and gas applications. The VLM20 utilizes a SMART multivariable transmitter with integral temperature and pressure sensor giving users an elegant all in one solution for their measurement needs. A precision 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 features a steam or gas mass flow accuracy of ± 1.5% of rate over a wide 30:1 flow range. Digital communications delivers 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.
