Slide the IS540.1 Smartphone (2) into the mount on the measurement electronics device (1).
Connect the plug (4) of the measurement electronics device securely to the 16-pin ISM
interface (3) on the smartphone (see Operating Manual IS540.1 Smartphone).
WAVEGUIDES FOR COLD (< -50 °C (< -58 °F)) OR HOT (> 120 °C (> 248 °F)) SURFACES
When performing measurements with the Waveguide, use the IS-SU150F1.1 Sensor Ultrasonic.
You can install the sensor outside or inside ex zones:
Unscrew the Waveguide (6) and slide the sensor (8) into the Waveguide Lock (7) with the
labeling pointing towards the spring.
Apply the couplant to the measuring surface of the sensor.
Screw the Waveguide back onto the Waveguide Lock.
SENSORS
For measurements without the Waveguide, use the IS-SU150F2.1 Sensor Ultrasonic or, optio-
nally, the IS-SU030F2.1 Sensor Ultrasonic (for quiet environments, with low leakage volumes).
You can connect these sensors to the measuring electronics (1) outside or inside ex zones:
Plug the sensor cable (5) into the connector labeled "SENSOR".
Connect the other end of the sensor cable to the sensor (8).
Clean the measuring area of the sensor with a soft, lint-free antistatic cloth.
When using the IS-SU150F2.1 Sensor Ultrasonic, stick the coupling foil onto the measuring
surface of the sensor.
When using the IS-SU030F2.1 Sensor Ultrasonic, apply the couplant to the measuring surface
of the sensor.
MEASUREMENT
DANGER
An incorrect procedure in explosion hazardous areas poses a risk of death or severe injuries!
Please pay attention to the following:
Ensure that the case is not brought into the potentially explosive area.
Make sure that the sensors, the Waveguide and the Waveguide Lock are earthed by the user
or another accessory approved by i.safe MOBILE GmbH when entering the potentially
explosive area.
Always place the sensors and the Waveguide on a grounded surface.
PREPARE MEASUREMENT
Make sure the valve is closed.
If possible, remove any existing insulation still on the valve. If the insulation cannot be
removed, access the measuring point through a hole in the insulation (diameter 10 - 12 mm
(0.39 - 0.47 in)).
Determine the valve ID (possibly label on the valve).
Determine the flow medium (possibly information on the pipe).
Check whether there is a pressure difference at the valve (possibly displayed on the pressure
gauge or via the process control system). For a correct measurement, there must be a pressure
difference according to the table in the „Device overview/Functions" section.
Determine the flow direction of the medium in the valve (possibly arrow on the pipe/valve).
