Applications: Fuel Consumption Measurement

- Fuel consumption is measured in order to study fuel-efficient vehicles and to determine differences in fuel consumption depending on driving methods.
- The following is an example of detecting the fuel flow rate (going side - returning side = actual amount of fuel used) from a fuel tank of a car or other vehicle to the engine.

What we can do with measurement
- The XFS series of flow sensors are compact and can measure even very low flow rates with high accuracy.
- The unique Periomatic™ calculation method enables high accuracy and high speed response to startup from a standstill, ultra-low speed, high speed, and sudden flow rate changes.
- The SPD/SPDL series can measure instantaneous flowrate/integrated flowrate switchably.
- PFC-4921 can display and measure both instantaneous and totalized flow rates simultaneously.

Selection Points
Flow sensor
- Capable of displaying and measuring from very low flow rates (XFS series)
- Pulse output is resistant to noise during long-distance transmission. 2.

Measuring instruments
- 0.5ms (TDP-49), 0.1ms (SPD series), 1ms (PFC-4921), 40ms (SPDL series) update analog output
- CAN communication with 1ms (SPD series) and 40ms (SPDL series) updates
- Periomatic™ calculation method for high accuracy and fast response even at ultra-low speeds
- Factory setting of the instrument and creation of a set value table are available when ordered as a set with a flow sensor.
