M20
Window for selecting fluid type
For standard liquids (no need to enter liquid sound speed) include:
(0) Water
(1) Sea Water (2) Kerosene (3) Gasoline
(4) Fuel oil (5) Crude Oil (6) Propane at -45°C
(7) Butane at 0°C (8)Other liquids (9) Diesel Oil (10)Caster Oil
(11)Peanut Oil (12) #90 Gasoline (13) #93 Gasoline (14) Alcohol
(15) Hot water at 125°C
M21
Window for entering the sound speed of non-standard liquids
M22
Window for entering the viscosity of non-standard liquids
M23
Window for selecting transducer type
There are 14 different types of transducers for selection.
If the
π
type spool-piece transducers are used, the user needs to configure the 3
transducer parameters.
Otherwise, the user needs to configure the 4 transducer parameters.
M24
Window for selecting the transducer mounting methods
Four methods can be selected:
(0) V-method (1) Z-method (2) N-method (3) W-method
M25
Display the transducer mounting spacing or distance
M26
Entry to store the pipe parameters into the internal NVRAM (non-volatile memory)
M27
Entry to read the previously saved pipe parameters
M28
Entry to determine whether or not to keep the last correct value when poor signal
condition occurs. YES is the factory default
M29
Window to set the threshold below which the receiving signal is defined as poor.
Valid number: from 000 to 999. 0 is the factory default
M30
Window for selecting unit system. ‘Metric’ is the factory default. The conversion
from English to Metric or vice versa will not affect the unit for totalizers.
M31
Window for selecting flow rate unit system.
Flow rate can be in
0. Cubic meter short for (m
3
)
1. Liter
(l)
2. USA gallon
(gal)
3. Imperial Gallon
(igl)
4. Million USA gallon
(mgl)
5. Cubic feet
(cf)
6. USA liquid barrel
(bal)
7. Imperial liquid barrel
(ib)
8. Oil barrel
(ob)
The flow unit in terms of time can be per day, per hour, per minute or per second. So,
there are 36 different flow rate units in total for selection.
M32
Window for selecting the totalizer unit
M33
Window for setting the totalizer multiplying factor
The multiplying factor ranges from 0.001 to 10000
M34
Turn on or turn off the NET totalizer
M35
Turn on or turn off the POS totalizer
