New V2 System™ Flow Meter With HART Simplifies Communication In Water & Waste Applications
October 3, 2016
Ideal For Water Wells, Pump Stations, Raw Water Influent, Reclaimed Water And Finished Water Effluent
With the addition of the HART® Protocol to the V2 System Flow Meter’s transmitter, the task of integrating flow measurement communications with control systems and other process equipment is now easier than ever -- increasing the V2 System’s applications flexibility in addition to its superior accuracy, space-saving design and total solution advantages in water and wastewater treatment applications.
HART is field-proven instrumentation communications technology that is easy-to-use and provides reliable two-way digital communication simultaneously with 4-20mA analog signaling. Applications include remote process variable interrogation, cyclical access to process data, parameter setting and diagnostics. Unlike other technologies, HART provides a unique communication solution that is backward compatible with the installed base of instrumentation in use today.
The V2 System Flow Meter is ideal in line sizes from 4 to 18 inches, wherever irregular or crowded piping and equipment conditions make other flow technologies impractical or unworkable due to the complex, costly construction needed to meet their longer straight-run piping requirements. It is simple to install, requires virtually no maintenance and features a long-life for a low life-cycle cost.
Pre-packaged and ready to install, the V2 System Flow Meter features a built-in 3-way valve that isolates the transmitter from the process fluid flow for easy maintenance without shutting down the pipeline. It arrives from the factory wet-flow calibrated, eliminating many of the common headaches that arise when adding a flow meter to any existing installations. The V2 System accurately measures flow over a wide flow range from 40 to 7500 gallons per minute, depending on the line size.
The V2 System’s cone actually conditions fluid flow to provide a stable flow profile that increases accuracy. The V2’s design features a centrally-located cone inside a tube. The cone interacts with the fluid flow and reshapes the velocity profile to create a lower pressure region immediately downstream.
The cone’s central position in the line optimizes the velocity of the liquid flow at the point of measurement. The result is a highly stable flow profile for measurement with accuracy to ±1% and ±0.1% repeatability over a wide flow range of 10:1. All of this is possible with a minimal straight pipe run of 0 to 3 diameters upstream and 0 to 1 diameters downstream from the flow meter.
In addition to excellent accuracy and repeatability over a broad range, the V2 differential pressure flow meter is suitable for a variety of applications, including water wells, pump stations, raw water effluent, reclaimed water and finished water effluent. It is also suitable for high pressure, high temperature and corrosive environment applications as well.
