We are looking at submtering multiple buildings and floors for a campus.
What is the advantage/disadvantage to using the following types of BTU meters:
1. Paddle wheel type
2. Ultrasonic
3. Electromagnetic
Which manufacturers do you recommend for a reliable meter?
I know where strainers are placed on piping diagrams, but when do you specify a basket strainer rather than a wye strainer? Is it based on pipe diameter, aplication, or other?
thanks!
