Safety Notes

The t-switch ATT11 is designed for flow limit detection in liquids

and gases. The ATT11 should be installed, connected,

commissioned, operated and maintained by qualified and authorised

personnel only, under strict observance of these operating instructions,

any relevant standards, legal requirements and where appropriate,

the certificate. Do not attempt to install or remove the instrument

under pressurised conditions.

Hold by housing or

extension tube; do

not hold by sensor.

Place sensor end

up. Sensor impact

may cause damage.

Guidelines for Threaded Process Connections

BSP 3/4" (G)

Use appropriately sized sealing

washer.

3/4" NPT

Use a suitable thread tape to achieve

a reliable seal.

Always use a spanner to tighten

the t-switch process connection.

Do not use housing to turn.

Note

For other types of process fittings follow standard good working practices.

Mounting and

Installation

Sensor Orientation Markings

Every process connection has an orientation mark stamped on it.

The locations of these marks are shown below and for optimum

performance it is important that it is facing the flow.

Mounting and

Installation

Sensor Orientation and

Flow Direction

It is important that the sensor is installed, such that the orientation

mark is positioned upstream to the flowing fluid.

If the sensor is not installed as above it may affect the performance

of the instrument.

Note

Welding instructions are provided with each sensor and care should be taken to read

them prior to installation. 6

Mounting and

Installation

Insertion Depth

For optimum measuring performance the active area should be

positioned anywhere between 5% and 50% of the internal pipe diameter.

The sensor tip should be in contact with the medium at all times.

Each form of process connector has an orientation mark that should

or = to sign be positioned in line facing the oncoming flow.

Good installation Practice Summary

Avoid installing in areas of extreme flow turbulence. For example;

Directly after bends or expansions/reductions.

Directly downstream of isolation and control

valves especially if partially opened.

Directly after pumps, fans and compressors.

Note

All downstream dimensions provided are to be used as a guideline only and whenever

possible greater dimensions should be considered.
