Measures steam flow

With a 50:1 turndown, the TVA steam flow meter from Spirax Sarco is a springloaded inline variable area meter that provides accurate measurements down to 1/50th of its maximum flow rate, ensuring all steam energy consumption can be accounted for.

The TVA is said to bring advantages, particularly when used in monitoring and targeting schemes that can create significant energy savings, but which depend on accurate measurement across all flow rates.

Just six pipe diameters of straight pipe upstream and three downstream are required for a smooth steam flow into the meter to ensure measurement accuracy.

Consequently, the meter can be installed without the need for costly pipe modifications.

Installation is quick and easy. The meter is a standalone unit that integrates flow sensing device, temperature sensor, connection accessories and flow computer into a compact unit, eliminating the need for additional external equipment. Spirax Sarco says that it can be installed in about half the time taken to install a meter with separate components.

The TVA uses a profiled stainless steel cone with a large, smooth surface area plated in hard chromium to resist erosion from wet steam, for a long and reliable operational life with recalibration rarely needed.

The meter is available with a choice of 4-20mA and pulse outputs for easy integration with energy management or control systems.
