The BURKERT 561233 Type S022 is a stainless steel insertion adapter designed to connect compact analytical ELEMENT measuring devices into piping systems. Specifically, the 561233 model is engineered for the conversion of Type S020 Bürkert fittings into Type S022 fittings. It features a G 1 1/2" external thread for the measuring device connection and is compatible with Bürkert fitting bodies ≥ DN 32. This adapter is universally applicable for Type 8202 (pH or oxidation-reduction potential transmitter) and Type 8222 (conductivity meter) ELEMENT measuring devices in pure, aggressive, or contaminated liquids.

Installation and Commissioning

Recommendations for Installing the Product on the Pipe

▶ To measure the pH or the oxidation reduction potential, install a U-shaped bypass in order to prevent the electrode drying out and to allow calibration without stopping the process.

▶ For all types of measurement, respect the following additional assembly conditions to ensure that the measuring device operates correctly:

• Respect the minimum distance between the measuring device and an injection point.

• Prevent the formation of air bubbles in the pipe in the section around the product.

• Ensure that the pipe is always filled in the section around the product.

Replace the Adapter of an S020 T-fitting with an S022 Adapter

1. Unscrew the 4 screws of the S020 adapter and remove it from the fitting.
2. Remove the seal in place.
3. Clean the surfaces on which the seal rests.
4. Insert the O-ring, delivered with the S022, under the fitting body.
5. Position the S022 adapter on the S020 T-fitting body.
6. Insert the 4 screws into the adapter.
7. Tighten the 4 screws in an alternating pattern to a torque of 1.5 N·m (1.1 ft·lbf).

Safety Instructions

DANGER

Risk of injury due to high pressure in the installation. ▶ Stop the circulation of fluid, cut off the pressure and drain the pipe before loosening the process connections.

Risk of burns due to high fluid temperatures. ▶ Do not touch with bare hands the parts of the product that are in contact with the fluid. ▶ Stop the circulation of fluid and drain the pipe before loosening the process connections.

WARNING

Risk of injury due to non-conforming installation. ▶ Fluid installation must only be carried out by qualified and authorised personnel with the appropriate tools. ▶ Observe the installation instructions for the measuring device inserted into the product.
