Assure an acoustically conductive path between the transducer face and the prepared piping surface, a coupling compound is employed. Enclosed with the Doppler flow meter system is tube of Dow Corning 111, silicone grease. This couplant is satisfactory for temporarily mounting the transducers to the pipe. If the installation is long-term (more than a few days), we recommends utilizing a silicone-based RTV such as Dow Corning RTV-732. If alternate couplant are utilized, the grease chosen must berated to not flow at the temperature of the pipe.
Spread an even layer of coupling compound, approximately 1/8 inch [3mm] thick, to the prepared transducer mounting areas of the pipe. Utilize Dow 111 for temporary mounting or Dow 732 for permanent mounting. 10Doppler Ultrasonic Flowmeter DF6100-EP Manual 11 Mounting of high temperature transducers is similar to Doppler flow meter standard transducers. High temperature installations require acoustic couplant Dow Corning 112 that is rated not to flow at the temperature that will be present on the pipe surface.
