SL1188 Ultrasonic Transit-time Flowmeter
Reversion: 3.0.0 Page 8of 74
1.3. Powering on
As soon as the flowmeter is switched on, the system will run automatically according to the last input parameters.
If the installation is accomplished when system is switched on, gain adjustment can be monitored in Window M01.
After code "*R" are displayed on the upper left corner of the screen, the system will activate the normal
measurement condition automatically. It is indicated by code "*R" on the upper left corner of the screen.
If it is the first time to use or install on a new site, the customer need to input the new installation site parameters.
Any parameters which are set by user will be saved permanently until they are changed by the user.
When the user modifies the parameters and removes the transducers, the meter will recalculate automatically, and
operate normally with the parameters.
The flowmeter can always complete all tasks at the same time. The tasks (Including measurement, output, etc)
will be carried out as usual, no matter in which display window. The system will default to the last window
settings and automatically display them when the flowmeter is power - on.

keys, where "11" is the window ID to
display the parameter for pipe outside diameter.

are shortcuts to the windows for Flow Rate, Velocity,
Signal Strength and Signal Quality, Totalizer, Velocity,
Transit Time Ratio, and System Error Codes.
1.5. Keypad Operation
The flow meter adopts the window software design to consolidate or subdivide all of the parameters entered, the
instrument setup and measurement result displays into more than 100 independent windows. The operator can
input parameters, modify settings or display measurement results by "visiting" a specific window. These windows
are arranged by 2-digit serial numbers (including "+" sign) from 00 ~ 99, then to +0, +1, etc. Each window serial
number, or so-called window ID code, has a defined meaning. For example, Window M11 indicates the parameter
input for pipe outside diameter, while Window M25 indicates the mounting spacing between the transducers, etc.
(Refer –Windows Display Explanations).
The keypad shortcut to visit a specific window is to press the
Menu
key at any time, then input the 2-digit window
ID code. For example, to input or check the pipe outside diameter, just press the
Menu
1 1
keys for window ID
code 11.
Another method to visit a particular window is to press ∧and ∨keys to scroll the screen. For example, if
the current window ID code is M02, press ∧key to enter Window M01, press the ∧button again to enter
Window M00; then, press the ∨key to back Window M01, and press the ∨key again to enter Window
M02.
Windows are separated into three types: (1) Data Type, such as M11, M12; (2) Option Type, such as M14; (3)
Pure Display Type, such as M01, M00.
You can check the corresponding parameters by visiting the Data Type Windows. If you want to modify the
parameters, input the digits and press Enter or press Enter first, input the digits then press Enter again to confirm.
