Product Specification
1. High flow rate range: 150 to 12000L/min(ANR).
2. Flow rate can be set and detected.
3. Three types of output: real-time switch output, accumulated switch output, or accumulated pulse output can be selected as an output type.
4. Digital displays of instantaneous flow rate and accumulated flow rate can be selected.
5. 4-channel Flow Monitor: 4 independent flow rate ranges can be monitored by a single controller.

*1) Flow rate display can be switched between the basic condition of 0°C, 101.3 kPa and the standard condition (ANR) of 20°C, 101.3 kPa, and 65% RH.
*2) For digital flow switch with unit switching function. (Fixed SI unit [(L/min, or L, m³ or m³×10³)] will be set for switch type without the unit switching function.)
*3) Accumulated flow rate is reset when the power supply turns OFF. It is possible to select a function that holds the accumulated value so it is not reset. In such cases, data is written on EEPROM (electrically erasable programmable read-only memory) at approximately four-minute intervals. When using, please take into consideration that the EEPROM writing is guaranteed up to 1 million times (four minutes × 1 million = 4 million ≈ 7.9 years)
*4) The high flow rate type is CE marking compatible; however, the linearity with applied noise is ±5% F.S. or less.
*5) Switch output and accumulated pulse output selections are made using the button controls.
*6) The analog output operates only for instantaneous flow rate, and does not operate for accumulated flow.
