High-precision fuel ｆlow meters that support automobile energy
conservation countermeasures. The global warming phenomenon is one of
several global environmental conservation problems that need to be
tackled, and the further reduction of fuel consumption is one of the
important issues currently being addressed. Ono Sokki has been
developing and supplying automotive-related measuring and control
instruments for over the past half century, with effort of satisfying
demands in the market and improving accuracy of instruments, especially
for fuel consumption measurement, which could be an essential part of
automotive tests. With selection of measurement module, the
FM-2500A/1500 digital flow meter can ensure high accurate measurement in
combination of flow detectors FP/FX/FZ series, according to testing
purpose. |

(FM-2500A only) |
|
Features
-
Three different flow detectors (FP/FX/FZ series) can
be used in combination with selection of suitable measurement module.
(Only the FM-2500A can be used in combination with the FX series flow
detectors.)
-
Liquid temperature, pressure, and density can be
measured and displayed as well as flow rate. (Density can be measured
when in combination with the FX series.)
-
Enables calculation of measured data and displaying
them as volumetric flow rate or mass flow rate.
-
Density correction function is provided to display of
the mass flow after correction of density based on temperature.
-
Measurement items can be displayed on a LCD in
various formats. (FM-2500A)
-
Difference of flow rate can be output by using an
addition/subtraction module with two measurement modules. (FM-2500A
only. FX series detectors cannot be used.)

density is available when simultaneous measurement with the
FZ series continuous mass flow meter is performed. (only

(*7) The position of the decimal point in the above table is
when the encoder pulse is set at “120 P/R x multiplier 10”
or “1200P/R (option)”. If the setting at “120P/R” is
selected, the decimal point moves to the right to increase
one digit. If the setting at “1200P/R x multiplier 10” is
selected, the decimal point moves to the left to decrease
one digit.
