TVA Flowmeters
Overview
Accurate and reliable measurement of your entire steam flow.
Unlike alternative technologies, the TVA Flowmeter allows you to measure the complete flow range.
Capturing all steam used within your maximum and minimum flowrate, allowing accurate and comprehensive steam energy management.
Measures your entire steam flow range.
50:1 turndown at best practice steam velocities.
Highly accurate - measurement helps to identify energy saving and waste reduction opportunities.
Easy integration and installation - within host control system and existing pipework.
Long operating life - well proven and highly robust design gives excellent reliability.
Low cost of ownership - with quick installation combined with excellent reliability.
