4.2 Individual Functions
No. Part Name Description
①
Body Consists of a measuring tube, straightener, and rectification mesh.
②
Sensor
Consists of two heat-sensitive resistance elements. Power supply (voltage and current)
to one of the heat-resistive resistance elements changes to maintain the heat resis-
tance at a constant level (approx. 30
°
C).
③
Transmitter
Changes in supply power (voltage and current) are transformed into a flowrate signal
which can be monitored on a -digit LCD display in terms of instant flowrate and total
flow.
④
Mode button Changes display modes to the instant flowrate or total flow. (See Sec. . for details.)
⑤
Reset button Used to reset the "Resettable total flow" to zero.
CAUTION: Do not attempt to disassemble the meter. If the flow path is badly contaminated
or a malfunction is suspected, contact the nearest customer service network in
your area. Unauthorized disassembly will void the warranty.
