Take advantages of excellent features of each Flow Sensor.
Laminar Flow Sensor (Laminar Flow Tube)► Wide variety of ranges (F.S.10 mL/min to 100 L/min)► Can measure pulsating flow rate such as pump discharge flow
► Durable & robust with no moving parts

Mass Flow Sensor► Can measure with different/variable line pressure► No atmospheric compensation required► High response speed■ Standard Features
Display

6 measurement screens are available.

Test Reliability

Blow Check

C-CHK

The flow is compared with the value ofFlow Master.

F-CHKMeasured flow is compared with the valueof Flow Master in every test. (Option: CX)

FormulaOptimizer
Flow Optimizer

After flow test, the fill valve is opened tocheck there is flow. Only for F4

Two-Point
Optimizer

Multi-Point
Optimizer

Samples the flows at Target Test Press(P1) to display the optimized flow.
Samples the flows at two pressure points,
Target Test Press (P1) and Off-Target Test
Press (P2), to optimize the measured flow
when the test pressure is off target.
Samples the flows at Target Test Press(P1) and other multiple pressure points
within the allowable range to optimize theflow when the test pressure is off target.

Data Analysis

Averages the readings for more stable readings with lessvariation.
Counter, Statistics, Waveform display

User Span

Span value is either manually entered or automatically set.

Flow Limits

Upper limits: UL2/UL, Lower limits: LL2/LL

Digital Filter

Exhaust Interference
Externally controls the Exhaust timing after air flow test.
Prevention

Data Acquisition

Up to 5000 data are stored.
USB can be used for data storing.

DET Extension

When the flow is in the range between “DET LL and DET
LL2” or “DET UL and DET UL2”, the DET is repeated.
External Exhaust Valve(Exhaust valve unit is sold separately)

Optional Feature
Bypass circuit ready(Bypass circuit unit is sold separately.)
