★RF-�T：　Field Indication Type(Instantaneous＋Integrated Indication)

This compact high-precision flow meter measures not only water and oils,but also chemicals. The rotations of two three-lobe elliptic gears output signals directly proportional to flow rates. Receiving the signals, the indicator provides field indication of instantaneous flow rates or integrated flow rate.

Rc1/8〜Rc3/8

1.5MPa	-5℃〜+40℃
1.0MPa	0℃〜+80℃

45〜85%RH

±1% ｏｆ readings

Instantaneous flow rate indication : 4digits
Integrated flow rate indication : 8digits

★Compact and rugged with liquid crystal digital indication that can be switched between integrated flow rate indication and instantaneous flow rate indication by the T/R▲ key.
★A lithium battery is incorporated for field indication alone,and the indicating section is dustproof and dripproof.(IEC IP67)
★Can be roated 90°between the detecting section and indicating section, allowing correspondence with the direction of flow in installation, anthe sensor section and indicating section can be separated(RF-�T-S）up to 30m at maximum.

★RF-�U：　（Electronic Transmission Type)
Field indication type(integrated type)
Remote transmission type(separate type) (instantaneous＋integrated 　indication＋analog output＋high/low alarm contact)
Pulse(contact)signals from the transmitter (RF-S) can be output variously by using a coverter in accrdance with the application. Integrated type(RF-�U）in which the transmitter (sensor section),converter and indicating section are integrated, and a separate type(RF-�U-S）are available.
