Ultrasonic
Spirax Sarco Ultrasonic meters clamp-on to the outside of the pipe and measure fluid through the use of ultrasound signals. They do not come into contact with the fluid and therefore do not create pressure drop, or contaminate fluid.
Spirax Sarco Ultrasonic meters have a low total ownership cost due to low installation and maintenance costs and are available in two options.
- Transit time – for clear fluid applications
- Doppler – for use in fluid applications with air bubbles or particulates.
Not all products are available in all markets. Please choose your National Spirax Sarco Web Site or Contact Us for further information.
