ConfidentialConfidential Completely fill the fluid passage with water. The product cannot measure correctly if the fluid passage is not completely filled. If the product is installed vertically, do not apply flow from the top to bottom. Bubbles may cause malfunction. Ensure the product is used within the operating temperature range. Operating temperature range is 0 to 50 o C, fluid temperature range is 0 to 85 o C. When multiple sensors are used in parallel, install them outside of the area shown below. 9 ． Cautions for handling (1) 50mm 20mm Uninstallable area

ConfidentialConfidential Positive ground power supply cannot be used. Short-circuit DC(+) DC (-) OUT1 OUT2 DC(+) The switch cannot be used for equipment in which piping or installation side is connected to DC(+). In order to identify ground, use a voltage tester and place it on the control board power source DC(-) and the tubing. If the measured voltage is 0V then it is a negative ground. If the measured voltage is 24V then it is a positive ground. Always assure that the customer is advised of this measuring method. Piping port and the metal part of the body are grounded to DC(-)/ blue line. 9 ． Cautions for handling (2)

ConfidentialConfidential 9 ． Cautions for handling (3) Use liquid with 5μS/cm or higher electrical conductivity. This product cannot be used for fluids with low electrical conductivity.

High repeatability.

ConfidentialConfidential Q&A (1) Gas fluid can be measured. (2) All types of coolant liquid can be measured. (3) Contaminated liquid may cause clogging. Filter is necessary. (4) Instantaneous flow and set value are displayed simultaneously. (5) Both integrated type and separated type can detect backflow. (6) If the product is installed vertically, do not apply flow from the top to bottom. Bubbles may cause malfunction. (7) Response time is fixed to 1s. (8) Maximum display and set values are the same as rated flow range. (9) Product can be used with any piping condition. (10) Electrical conductivity is a measure how well electricity flows.
