2 The debut of an innovative, Ultimate convenience has been separate-amplifier type flow First-in-the-world Featuring a flow indicator for visual display of the flow Flow display Alarm display Displays the flow condition with indicator movement that visually shows the instantaneous flow rate Displays the condition of detected errors such as water shortage Compact sensor head FD-P/F Industry thinnest Space-saving 2-mm width The sensor head has achieved the thinnest width in the industry 2 mm wide.* The housing width was shrunk to be as close as possible to the diameter of a pipe, saving piping space. This helps with downsizing the facility because several sensor heads can be mounted side-by-side onto pipes that are in close proximity to each other. * FD-Fxx model (PFA head) High-accuracy Hybrid detection system using eddy + ultrasonic The FD-V7 Series has adopted the eddy + ultrasonic detection method. It ensures stable and accurate flow rate measurement by detecting eddies with an ultrasonic device instead of a piezoelectric device that is easily affected by vibration. The fluidpassing section has a one-piece structure that makes maintenance easy. Conventional model: The sensor head requires a large mounting space. FD-P/F: The sensor head requires an extremely small mounting space. Internal structure Can be mounted onto pipes installed in close proximity to each other Receiver Eddy generator Flow Housing Transmitter Ultrasonic wave The sensor uses ultrasonic waves to detect eddies that are generated when the liquid flow hits the eddy generator. & Wide range of sensor head variations The sensor heads are divided into two types: The PPS head, a general-purpose type that is resistant to oil and chemicals, and the PFA (fluorine plastic) head that can be used for acids, alkalis or ultrapure water. The optimal sensor head can be selected from five models according to the target liquid and the flow rate. PPS PFA PPS head PFA head FD-P5 FD-P2 FD-P5 Type Detectable flow rate PPS.5 to 5 liters/min. 2 to 2 liters/min. 5 to 5 liters/min. FD-F4 FD-F2 Type PFA Detectable flow rate.4 to 4 liters/min. 2 to 2 liters/min. General-purpose type resistant to oil and chemicals [: FD-Pxx] (PPS: Polyphenylene sulfide) One-piece structure of fluorine plastic including tubes All surfaces in contact with liquid are made of fluorine plastic. The PFA head is suitable for controlling the flow of various strong chemicals such as the pure water used in the semiconductor manufacturing line. [: FD-Fxx] Heat resistant Up to 1 C The FD-V7 Series sensor head resists temperatures up to 1 C, enabling detection of hot liquid such as the hot water for heating plastic molding dies. Easy maintenance Convenient joint connector (PPS head only) The joint connector design facilitates screwing the sensor head side into the connector during the piping installation or replacing the sensor head for maintenance. * A 1 m extension cable is also available (optional, OP-51475). Clean pack The sensor head is shipped in a clean pack (vacuum-sealed pack). There is no problem with using it for flow control in the semiconductor process line. 2

3 separate-amplifier type flow sensor realized in the form of a space-saving, sensor that can be mounted anywhere. Fixing ring Connector-type wiring Connector cover A connector with a protection cover has been adopted. Easy-to-use, digital display amplifier FD-V First-in-its-class 2-level display & direct access The bright, viewer-friendly 2-level display allows you to adjust the setting value while checking the current flow. Pressing the manual button enables direct access to the setting value for adjustment. Selectable mounting DIN-rail and panel mounting available Two types of mounting methods can be selected: DIN-rail mounting and panel mounting. Since the amplifier is separate from the sensor head, it can be mounted to any viewer-friendly location according to the facility. Output indicator Current value display (red) MODE button Setting value To switch between the display (green) display and operation modes FD-V7 (P): DIN-rail mounting type Manual buttons To adjust the sensitivity manually DIRECT ACCESS To access the setting value directly FD-V75 (P): Panel mounting type 48 mm Easy connection, easy maintenance Connector-type wiring Both the sensor head cable and the power supply/input cable can be easily connected or disconnected with connectors. This design allows efficient cable connection and sensor mounting as well as easy maintenance. The FD-V7 (P) can be mounted easily onto the DINrail. It can be added to the existing facility easily. The FD-V75 (P) is designed to be mounted on a control panel. The amplifiers can be mounted in 24 mm 48 mm 24 mm contact with each other, thus saving space when several amplifiers are mounted. Selectable detection modes Various detection modes are featured as standard. The upper/lower limit detection mode produces independent outputs when upper and lower limit values are detected, the window mode indicates whether the detected value is within the upper and lower limit values, the cumulative flow mode checks the cumulative value, and the bank switching mode allows two settings to be switched with external input. The optimal mode can be selected according to the application. Upper/lower limit detection Selectable output modes Window Cumulative flow Bank switching Several output modes are featured as standard. The free-range analog output allows the range of analog outputs to be specified as desired, and the multiplied pulse output allows 5 selections of multiplication factors and can be used for the control of minute flow. Various needs for flow control can be satisfied. Abnormal alarm output ALM When detection is disabled due to water shortage or bubbles, the abnormal alarm is output. This output can be used to cancel the detection signal or to manage the error history. Power save function Eco If the numeral value display is unnecessary, the display can be turned off to be in economy mode. Normal display Shifts to economy mode in three minutes (The green bar display flashes.) Returns automatically to the normal display with the press of any button.

The FD-V7 Series resists temperatures up to 1 C, enabling detection of hot liquid such as the hot water for heating plastic molding dies. Pure water/chemicals Controlling the flow supplied to die casting dies Controls the flow of cooling water supplied to die casting dies through thin pipes. Since the sensor head is compact, several heads can be installed onto pipes installed in close proximity to each other. Controlling the supply of solution in a PC board cleaner Controls the flow of cleaning solution used in a single wafer processing cleaner. Since the PFA type sensor head is made of fluorine plastic, it can be used for detection of various chemical solutions and pure water. 4 Controlling the supply of wafer cleaning solution Controls the flow of the cleaning solution used for effective wafer cleaning and the pure water used for rinsing. Since the PFA type sensor head is made of fluorine plastic, it can be used for detection of various chemical solutions and pure water.

Selectable operation mode/output mode F-1 (Upper/lower limit detection mode) F-2 (Window mode) F-3 (Cumulative flow mode) Two detection points of instantaneous flow rate can be specified as desired. The hysteresis range can also be specified. The upper limit value (P2) and the lower limit value (P1) can be specified as desired. When the instantaneous flow rate goes out of range between P2 and P1, the sensor turns off. The hysteresis range can also be specified. This mode provides a pulse output proportional to the flow rate. This mode is used to specify two detection points of the cumulative flow rate.

These settings can be switched by turning the external input on or off. The hysteresis range can also be specified. When the external input is turned off P2 P1 When the external input is turned on B2 B1 In the F-1/F-2 mode, disabling the abnormal alarm output enables the analog output. The analog output produces output between 4 and 2 ma for values between the lower limit (A-L) and upper limit (A-H). A-L and A-H can be specified in 1% increments to full scale. The initial values are: A-L is % and A-H is 1%.
