Page 3: About The Transducer
ABOUT THE TRANSDUCER The Echomax XPS / XCT series of transducers transducer operates in association with Milltronics ultrasonic level monitoring products. The transducer converts the electrical energy of the transducer face transmit pulse from the transceiver into acoustical energy. It then converts the acoustical energy of the echo back into electrical energy for the –... -

Page 6: Do's And Don'ts
On liquid applications, the transducer must be mounted so that the axis of transmission is perpendicular to the liquid surface. On solids applications, a Milltronics Easy Aimer should be used to facilitate aiming of the transducer. Do not overtighten mounting . Hand tightening of the mounting hardware is sufficient. -

- Page 13 LIQUID APPLICATIONS - STANDPIPES In many applications access must be made via a standpipe. In such cases, Milltronics can provide factory bonded flanged transducers or split flange kit that will readily mate to the flanged standpipe. Another option is to hang the transducer from a blind flange.
