1. To screw the nut smoothly, please add the lubricant to nut ③
and threads. (Fig.4)
Notice: It is disallowed to add lubricant on the probe.
2. Screw a suitable adapter ② to the joint ① . (Fig.4)
3. Insert the sensor to the adapter and then screw the nut ③
The Max screwing torque: 50Nm. (Fig.4)
4. The insertion depth for the probe: The minimum insertion
depth to the pipeline ≧ 12mm. To ensure correct depth, the
user can use ema adapter. (optional order)

· Adjust to the min. flow/flow stop. The sensor detects the
current flow and sets the value as the smallest display value of LED.
In the normal operation, the first green LED(LED 0) flashes when
the flow lower than this value (or when the flow stops).
Notice: LO-Teach operation is only allowed to be done after HI-Teach

extended length of probe 100/200 mm, and titanium
alloy probe for corrosion protection for your choice.
1. Please confirm the purchasing item is switching
or analogue or Relay output and install the
product according to the operating voltage.
2. For AC RELAY sensor, add the fuse ≤5A (Fast
action) or cable with shield.
