keys and to scroll up and down to the proper
liquid, and then press key.
6) Press key to enter into M23 window. Press
key to get into the option selection mode. Use
keys and to scroll up and down to the proper
transducer type, and then press key.
7) Press key to enter into M24 window. Press
key to get into the option selection mode. Use
keys and to scroll up and down to the proper
transducer mounting method, and then press
key.
8) Press key 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
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
key will lead to window M90 for
displaying diagnostic data. Press key again to
return to the previous window. Press the key to
go to window M11.
When the current window is M25, pressing
key
will lead to window M01.
2.7 TRANSDUCER 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 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. The longer the better. The transducers
should be installed at a pipe section where the length
of the straight pipe at upstream side is at least 10D
and at downstream side is at least 5D. Besides, 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 on the location does not
exceed the range for the transducers. Generally speaking,
the closer to the room temperature, the better.
4. Select a relatively new straight pipe line if it is
