IV. MECHANICAL INSTALLATION
generAl instAllAtion guidelines
• Aim the transducer perpendicular to the surface of liquids.
• Provide sufficient flexible conduit at the transducer location to facilitate transducer aiming movement
and removal.
• Run transducer cable from the transducer to the junction box, and from the junction box to the controller
in dedicated grounded metal conduit or in cable tray. All cables connected to the same controller may be
routed in the same conduit.
WArning: do not run trAnsducer cAble With Any other Ac PoWer Wiring.
Mounting instructions
To configure the full system, the following will need to be mounted and/or installed
1. Transducer into the tank or vessel
2. Temperature Probe (optional)
3. Junction Box
4. UltraWave Controller
Mounting trAnsducers
For optimum results, a clear sound beam path between the transducer and the lowest level of material is
required.
See Figure 2: Positioning Transducers for Optimum Results with Level Applications. When selecting a mounting
location for the transducer, follow these guidelines:
• Minimum distance from the transducer to any sidewall is the greater of the following:
— 1’ (0.30m) horizontal distance for each 10’ (3.0m) in vertical distance from the face of the transducer
to the zero level (no material in the vessel)
— 2’ (0.60m) horizontal distance
Note: For a very deep vessel with a small cross-section, it may be impossible to meet the above requirements.
• Transducer beam path is outside the path of the fill stream.
• Transducer beam path is away from splashing or agitating liquid or bouncing materials.
• Ladders, seams, rebar, etc. in the transducer beam path are avoided or eliminated.
• Transducer location is away from equipment which create vibration and noise that can interfere with the
operation of the system: dryers, motors, compressors, fans, blowers, air conditioning units, etc.
• Face of the transducer is above the maximum expected material level by a minimum of:
— 12” (305 mm) for 56T-25 transducers
— 24” (610 mm) for 56T-50 transducers
