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 (see Operating
Manual).
Determine the flow direction of the medium in the valve (possibly arrow on the pipe/valve).
PERFORM MEASUREMENT
Turn on the smartphone and open the Senseven App.
Follow the on-screen instructions.
You can find help on how to use the Senseven App at www.senseven.ai
Once you have selected the valve type in the Senseven App, the app will show the ideal
measuring points (M1, M2, etc. in the valve drawing), specifying where you have to place the
sensor for the measurement. In general, the ideal distance between the measuring points
depends on the pipe diameter and is measured from the valve flange:
