Pipe Size:
The three-digit code indicates the inner diameter of the pipe, e.g., 050 means DN50.

Example of Model Selection:
For an application involving saturated steam with a process pressure of 0.8Mpa and a flow rate of 800~4000kg/hr, using a DN100 (4”) ANSI flanged process connection with RS485+PULSE output and 24VDC power, the model number could be VFM60-N-T1313S9N100 or VFM60-M-T1313S7N100.

Counter Ordering Information:
At 0.8Mpa, the density of saturated steam is approximately 4.162kg/hr at 170 degrees C. The velocity range of 2~70 m/s is within the standard measurement range.

Counter Solution:
The model number for this solution is VFM60-N-T1313S9N100 or VFM60-M-T1313S7N100, suitable for ANSI flange, 0.8Mpa saturated steam, with temperature compensation and RTD required or choosing a multi-variable version.

Catalog excerpts

Comate Intelligent Sensor Vortex flow meter datasheet VFM60 Vortex Flow Meter VFM60 is a powerful flow meter utilizing “Karman vortex” theory, which can meet the requirement of measuring the flow rate of various fluids such as gas, steam and liquid. The product uses the VFM60 transmitter technology, which provides with the excellent signal processing capability and enhance the vortex metering technology to a new level, which means it has lower measuring limit, better stability and accuracy. The unique dual-sensor design and special signal processing method has also ensured a better anti-vibration by eliminating the vibration signals to provide more reliable performance and lower measurement limit. The VFM60 platform is also an open platform, which means we can keep on upgrading its function according to customer’s unique requirement, and make the product a highly custom-orientation product. ⚫ ⚫ ⚫ ⚫ Sensor design that free from maintenance. Self-diagnose function, ensure easier trouble-shooting. Unique dual sensor technology excellent in anti-vibration. Self density calculation function is optional, can calculate density and mass flow rate without mass flow computer. Can output mass flow rate, temperature and pressure by working with separate RTD and pressure transmitter. Muti-variable version with built-in RTD and pressure sensor to measure standard/mass flow directly and display flow rate, temperature, pressure, mass flow rate and density as requires. Unit selectable function, meet different requirement from different area. Blue tooth function optional, can read flow rate and other data on COMATE APP with and smart phone or pad.
