In coating facilities for beverage cans, cars, truck bodies, etc. air flow velocity needs to be measured accurately at different points:
- laminar flow has to be ensured in the spray booth to get optimal results and
- the exhaust air in the coating booth and the chamber kiln have to be monitored for safety and environmental reasons.
Ultrasonic transit time flowmeters measure the flow velocity by 2 transducers clamped on outside the pipe for sending and receiving ultrasonic signals:
- easy installation and retro fitting - no pipe cutting
- no flow interruption during installation and maintenance
- no moving parts - no wear and tear
- for pipe sizes from 25 up to 5000 mm
- unaffected by density, concentration or temperature
- rugged and reliable
Diaphragm seals are used to protect pressure instruments from corrosive, viscous, clogging or hot process media and safeguard highly hygienic and ultra pure liquids from contamination.The seals and membranes are customized for a variety of applications with different materials, coatings and linings, mounting and connection types.
