• Installation
- Location -
Do not locate the FLR series sensor near inlets/outlets.
If there is surface wave action, then use a time-delay relay or stilling tube. If a
stilling tube is used, drill vent holes in the tube and use a spacer to assure the
float has free travel inside the tube.
Wave action may cause switch to chatter. Use a stilling tube or time-delay
relay to prevent switch chatter.
- Mounting -
The FLR can be mounted up to 30 0 from vertical.
1. Flange Mounting
Provide the compatible mating flange on the tank and install using a suitable
gasket.
2. Plug Mounting
Provide the compatible female boss on the tank and install the FLR with a
suitable gasket, O-ring, or thread tape.
