II. Installation and Operation
The clamp-on type ultrasonic flow meter allows for the simplest and the easiest installation of all types of flow
meters, though careful attention in selecting the measurement point, inputting pipe parameters, fixing the
transducers onto pipe, etc. in order to ensure accurate and reliable measurement of flow is needed. In this
chapter, you’ll be introduced to how to select the measurement point, input parameters, select mounting
method, etc.
1. Selecting the Measurement Point
Selecting the right measurement point is the most important factor for ensuring the accuracy and should be
done according to the following steps;
(1) Make sure the pipe to be measured is full.
(2) Select a location where it allows for straight pipe run of 10D upstream and 5D downstream. In case
there’s a pump or a bending section in the upstream, increase the upstream run to 30D in order to allow the
flow to fully develop into stable flow profile.
(3) Ensure the temperature at the measuring point is within the specified range.
(4) Avoid sections where the inner wall of the pipe is scaled or rusted that can negatively affect the
performance of the meter.
2. Setting the Parameters
In order to get the correct transducer mounting distance (the distance between the front edges of both
transducers), verify and set the following parameters;
(1) Pipe outer diameter
(2) Pipe inner diameter
(3) Pipe material
(4) Liner
(5) Fluid type
(6) Transducer type
(7) Transducer mounting method type
When the above parameters are properly set, the correct transducer mounting distance is calculated and
displayed in menu M25. Then the machine searches for proper amplifier gain. After S1, S2, S3 and S4 steps,
the machine enters into the normal operation state.
