Equipped with all the required functions and performance for the measurement of fuel flow
Three simultaneous ways to measure the flow Instantaneous, time-averaged flow, and total flow
Voluminous measured data output Analog, USB data, and pulse output
【High-speed analog output】
Updated analog output every 1ms at high speed. Rapid variations in the fuel flow are measured with precision. And it can be used in connection with measurements to verify correspondence with the throttle opening.
【Display switching】
You can switch and view different measurement displays even when taking measurements. Using the “MONI” key, you can conveniently switch the display between 4 patterns of the 8 different types, the instantaneous flow, the average flow of total time, the total flow, the total time, the previous total flow, and the previous total time, as well as the pressure and temperature.
【Automatic measurement using the time-up function】
It is possible, for example, to set the total time in advance as 20 seconds and make repeated measurements of the average flow over 20 seconds. Data for the instantaneous flow, temperature, and pressure are continuously measured in real time.
