** IP66：The IP Code, International Protection Marking, IEC standard 60529, sometimes interpreted as Ingress Protection Marking, classifies and rates the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water. The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects. The second digit indicates the level of protection that the enclosure provides against harmful ingress of water. First 6 stands for dust tight: No ingress of dust; complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow.

*** This machine is calibrated with normal temperature water and CNS UPVC pipe before delivery. Different environments and different fluids will result in different performance.

Device Functionalities

LED screen mainly provides high contrast numbers display for high visibility even in a dark environment.

LED screen also provides 5 displayed digits within a decimal point which mainly displays real-time and accumulated flow volume data. For more digits of data, such as historical data and long-term cumulative data, please look at the LCD screen.

LCD screen allows display for 16 English characters in 3 rows . The first row is current content with units. The second row is data. The third row is a definition of each button.

The LCD screen has a 3-color backlit display. Definition of each color light as below:

• Green: Real-time data, device is working normally.

• Blinking red light: Alarm A- Major error. Please see the “Alarm and Description of System Conditions” page for more details.

• Steady red: Alarm B host meets the conditions specified by the user, or for Alarm C maintenance matters, please see the warning page.

• Orange: The device is normal, and the display screen is on the setting page.

There are 4 buttons on the device, the definition of each button will be displayed at the upper row on the LCD screen. Generally, the leftmost button stands for “Exit” or “Back to last page”. The middle 2 buttons are for users to review page by page, modify data, or switch options. The rightmost button stands for “Set” or “Confirm”. Previously mentioned definitions are only for general use. For some other usage scenarios, button definitions are modifiable for usability or error proof.
