FLEXIM’s new small black coupling pads are said to add to the long term durability of clamp on ultrasonic flow meters. The pads serve as the right acoustic coupling contact.
One of the advantages of non-contact ultrasonic flow meters is their low maintenance requirement.
The flow transducers are simply attached to the outside of the pipe. They are not in contact with the medium to be measured and are thus free from wear and tear.
The only important condition for proper functionality is a good transmission of the acoustic signals through the entire pipe and back.
Normally a paste is used to achieve this coupling between the transducers and the pipe. Depending on on-site conditions this paste needs to be re-applied from time to time.
Flexim’s coupling pads are made from materials that can tolerate high temperatures and retain their elasticity over long periods without the need for frequent maintenance.
The coupling pads take the place of such coupling pastes between the transducers and the pipe. They are held in place and pressed against the pipe with properly designed pipe mount fixtures.
The pad material is flexible and durable enough to maintain the acoustic contact. There is no longer the need to re-apply any pastes.
