to enter into M25 window. The transducer installation distance will be
displayed on the window. Based on this distance, install the transducers on the pipe now.
After installation is completed, press ENT key to go to M01 window to check if the
measurement result is good.
The first-time users may need some time to get familiar with the operation. However, the
user-friendly interface of the instrument makes the operation quite easy and simple. You will
soon find that it is actually very quick to configure the instrument with very little key
pressing, since the interface allows the user to go to the desired operation directly without any
extra steps.
The following tips will facilitate the operation of this instrument.
(1) When the current window is one between M00 to M09, pressing a number key x will
enter into the M0x window directly. For example, if the current window display is M01,
pressing 7 leads to window M07.
(2) When the current window is one between M00 to M09, pressing ENT key will lead to
window M90 for displaying diagnostic data. Press ENT key again to return to the
previous window. Press the . key to go to window M11.
(3)
When the current window is M25, pressing ENT key will lead to window M01.
2.7 Transducers Mounting Allocation
The first step in the installation process is to select an optimal location for installing the
transducers in order to make the measurement reliable and accurate. A basic knowledge about
the piping and its plumbing system would be advisable.
An optimal location would be defined as a long straight pipe line full of liquid that is to be
measured. The piping can be in a vertical or horizontal position. The following table shows
examples of optimal locations.
Principles to select an optimal location:
(1)
The straight pipe should be long enough to eliminate irregular-flow-induced error.
Typically, the length of the straight pipe should be 15 times of the pipe diameter (15D),
the longer the better.
The transducers should be installed at a pipe section where the length of the straight
pipe at the upstream side is at least 10D and at downstream side is at least 5D.
Additionally, the transducer installation site should be at least 30D away from the pump.
Here D stands for pipe outer diameter. Refer to the following table for more details.
(2)
Make sure that the pipe is completely full of liquid.
(3)
Make sure that the temperature of the mounting location does not exceed the range for
the transducers.
