Installation
Explosion hazard. The instrument is not approved for installation in hazardous locations.
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Usually, the typical Flo-Tote 3 installations do not receive electromagnetic interferences. But, because of the
velocity measuring method used in the AV probe, electrical machinery or radio transmitters near to the installation
can cause measurement errors. Keep cable lengths as short as possible to prevent electromagnetic
interferences. Also, be careful in the routing or collection of cables to keep this effect to a minimum level.
Items to collect
Collect the items that follow to install the sensor. The items that follow are supplied by the user.
• Sensor installation hardware
• Socket and ratchet wrench
• Tie wraps
• Electrical tape to wrap the cable and installation hardware together (optional)
Site location guidelines
For the best accuracy, install the sensor where the flow is not turbulent. The ideal location is in a
long, straight channel or pipe. Outfalls, vertical drops, baffles, curves or junctions cause the velocity
profile to become distorted.
