Note 1: The minimum size required for the solids or bubbles is 100µm and the minimum concentration
is 75 ppm.
Note 2:
◆ Physical water flow testing device manufactured by Finetek. Fluid temperature: 20±10°C;
environment temperature: 20±5°C
◆ Length of straight piping section: Upstream – 15 D or over; downstream section: Over 5 D
◆ When operating in the regular environment, the value after the following calculation process
will be considered: linearity +measuring error+ repetitive accuracy.
◆ Additional errors to the measured value due to the type and status of the pipeline used in the
site, as well as the fluid type and fluid temperature, may occur.
LCM 128*64-pixel, backlight type
