Temperature & Pressure Operating Limits. Proteus Industries 1000 Series

Adjustable Fittings

1. Ensure that the locknut is positioned so the back-up washer is in contact with the beginning of the threads farthest from the end of the fitting.

2. Screw the fitting into the port until the back-up washer contacts the sealing face.

3. Check to be certain that the o-ring fits easily into the non-threaded receiving area of the port, and is not pinched or damaged.

4. Unscrew the fitting a maximum of one turn to position it in the desired direction.

5. Tighten the locknut firmly against the back-up washer so the fitting assembly is held securely in place.

Filtering

Your circulating fluid may contain particles. While not essential to the operation of the flow sensor, it is good practice to filter your fluid. A 100-micron filter is often used to remove rust and other particles from the fluid.

This can increase the usability lifetime of pumps and other fluid system components as well as reduce wear in the sensor.

NOTE

L

The Temperature Limit is the fluid temperature that can be sustained with the flow switch cooled by ambient air at 20°C.

Customized versions of 1000 Series flow switches have been proven in operation with fluid temperatures from -40°C to 170°C.
