- Safety Precautions
- Precautions for Correct Use
- (1) Use clean fluids. Install a filter or mist separator on the inflow pipe. Failure to do so may result in malfunction or changes in characteristics due to dust or mist. This does not apply to the D6F-W, D6F-V, D6F-P and D6F-PH.
- (2) Do not use corrosive gases other than the specified applicable fluids (such as chlorine, sulfur, acid,or alkali) . Doing so may cause product failure.
- (3) The specified performance may not be obtained if the D6F is used for fluids other than the specified applicable fluids.
- (4) After removing the Sensor from the package, do not allow foreign particles to enter the piping. Foreign particles in the piping may cause product failure.
- (5) Install the sensor so that the fluid flows in the direction indicated by the arrow on the Sensor. Correct measurements cannot be obtained if the fluid flows in the wrong direction. This does not apply to the D6F-V, D6F-P and D6F-PH.
- (6) It is recommended that the Sensor (except for the D6F-A3) be mounted horizontally. If it is not mounted horizontally, an error of ±1% FS or higher may result.
- (7) Install the Sensor on a flat surface. Incorrect installation may damage the Sensor and make it impossible to obtain correct measurements.
- (8) Make sure that the power to all equipment is turned OFF before you install the Sensor. Installing the Sensor while the power supply is ON may result in electrical shock or abnormal operation.
- (9) Always check operation after installation.
