| Learning Notes |
|
- An ultrasonic sensor should always be mounted perpendicular to the liquid surface
- A VitonÆ mounting gasket should always be used when installing the sensor
- Avoid fitting types or shapes with thick mounting structures located around the transducer threads greater than 3/8"
- We recommend using Flowline plastic fittings, or equivalent, with thin wall mounting structures that isolate the transducer
|
Bulkhead Fittings- For 2" sensors, use Flowline's LM52-2890 low-profile 2" bulkhead fitting
- For 1" sensors, add a LM52-1001 2" x 1" thread by thread reducer bushing
- Avoid bulkhead fittings with internal threads or pipe stops forward of the installed transducer
|
Flanges- Always use a flange with the mounting threads above the plain of the flange
- For 2" sensors, use Flowline's LM52-2890 2" flange
- For 1" sensors, add a LM52-1001 2" x 1" thread by thread reducer bushing
- If using a blind flange, tap a female thread 1" larger than the sensor's transducer size and use the appropriate reducer bushing
|
Riser- To avoid acoustic interference, follow the maximum riser height versus inner diameter
- Riser height is defined as the distance from the installed face of the transducer to the opening in the tank
- The inner diameter dictates the maximum riser height that the sensor can be installed on
|
Reducer Bushing- A reducer bushing will provide good isolation of the ultrasonic signal when mounted
- Use a reducer bushing that isolates the sensor with a gap between the inner and outer threads
- Use Flowline's 2" x 1" thread by thread LM52-1001 reducer bushing for all 1" sensors
|
Side-Mount Bracket- For installation on open tanks, use Flowline's LM50-1001 bracket (The LM52-1001 has a 2" female thread)
- Flowline's LM52-1001-1 includes a 2" x 1" thread by thread reducer bushing for 1" sensors
