Part One: Ultrasonic Flowmeter Menus
Part one: Ultrasonic Flowmeter Menus
The flow meter user interface comprises about 100 independent windows, numbered by M00,M01,M02……. M99,M+0,M+1 etc.
There is no need remembering all the menu windows, while it is strongly suggested to keep in mind the most commonly used command windows and the proximate window numbers of some uncommonly used windows. You can always press ‘UP’ or ‘DOWN’ keys to move to the position you expect.
NOTE: 1. It is important to practice those menu windows on your flow meter while reading this chapter for the sake of understanding and familiarity.
2. For quick and easy access to certain information, simply press the ‘MENU’ key followed by the window number (a two-digit number). To exit from one window to the next, press ‘UP’ or ‘DOWN’ keys.

Function |
|
M00 |
Display flow rate and NET totalizer If the net totalizer is turned off, the net totalizer value shown on the screen is the value prior to its turn-off. Select all totalizer units in menu M31. If the UP key is pressed , display will go to M90. |
|
M01 |
Display flow rate, velocity |
|
M02 |
Display date time and POS (positive) totalizer. If the positive totalizer is turned off, its value shown on the screen is that prior to its turn off. |
|
M03 |
Display flow rate and NEG(negative) totalizer If the negative totalizer is turned off, its value shown on the screen is that prior to its turn-off. |
|
M04 |
Display date and time, flow rate. The date and time setting method is found in M60. |
|
M05 |
Display energy rate (instantaneous Caloric)and total energy (Caloric). |
|
M06 |
Display temperatures, Supply T1, Return T2. When BTU is selected, The temperature is in Fahrenheit. |
|
M07 |
Display analog inputs, AI3/AI4, current value and its corresponding temperature or pressure or liquid level value. |
|
M08 |
Display all the detailed error codes. Display working condition and system error codes. ‘R’ stands for normal, others refer to Chapter for details. |
|
M09 |
Display today’s total NET flow. |
|
M0. |
Display the input user’s data sent in through the RS-485 serial port. This display will be useful in a network environment to display extra information generated by the host computer. The command format is UINFO=[40 bytes of user’s data, the first 20 bytes of which will be displayed on the first row , the last 20 bytes on the second] NOTE: The display has to be renewed with every boot up of the flow meter. |
|
M10 |
Window for entering the outer perimeter of the pipe. If pipe outer diameter is known, skip this menu and go to Menu 11 to enter the outer diameter. If 0mm is entered, a simulation procedure will be started. The velocity is set to 1.23456m/s, and the instantaneous flow to 0 m3/s, and the working status is ‘R’. |
|
M11 |
Window for entering the outer diameter of the pipe. Valid range: 0 to 18000mm. NOTE: you just need to enter either the outer diameter in M11 or the peripheral in M10. If 0mm is entered, a simulation procedure will be started. The velocity is set to 1.23456m/s, and the instantaneous flow to 0 m3/s, and the working status is ‘R’. |
|
M12 |
Window for entering pipe wall thickness. You may skip the menu and enter inner diameter in M13 instead. |
|
M13 |
Window for entering the inner diameter of the pipe. If pipe outer diameter and wall thickness are entered correctly, the inner diameter will be automatically calculated, thus no modification need to be made in the window. |
|
M14 |
Window for selecting pipe material Standard pipe materials (no need to enter material sound speed ) include: (0) carbon steel (1) stainless steel (2) cast iron (3) ductile iron (4) copper (5) PVC (6) aluminum (7) asbestos (8) fiberglass (9) other( need to enter material sound speed in M15) |
|
M15 |
Window for entering the pipe material speed, only for non-standard pipe materials. |
|
M16 |
Window for selecting the liner material. Select NONE for pipes without any liner. Standard liner materials(no need to enter the liner sound speed) include: (0) None，No Liner (1) Tar Epoxy (2) Rubber (3) Mortar (4) Polypropylene (5) Polystryol (6)Polystyrene (7) Polyester (8) Polyethylene (9) Ebonite (10) Teflon (11) Other (need to enter liner sound speed in M17) |
|
M17 |
Window for entering the non-standard liner material speed. |
|
M18 |
Window for entering the liner thickness, if there is a liner. |
|
M19 |
Window for entering the ABS thickness of the inside wall of the pipe. |
|
M20 |
Window for selecting fluid type. Standard liquids(no need to enter fluid sound speed) include: (0) Water (1) Sea Water (2) Kerosene (3) Gasoline (4) Fuel oil (5) Crude Oil (6) Propane at -45C (7) Butane at 0C (8)Other liquids(need to enter sound speed in M21 and viscosity in M22) (9) Diesel Oil (10)Caster Oil (11)Peanut Oil (12) #90 Gasoline (13) #93 Gasoline (14) Alcohol (15) Hot water at 125C |
|
M21 |
Window for entering the sound speed of non-standard liquid, used only when option item 8 ‘Other’ is selected in M20. |
|
M22 |
Window for entering the viscosity of the non-standard liquids, used only when option item 8 ‘Other’ is selected in M20. |
