in PPO materials which is internationally accepted as meets the
purified water requirements and fits for saving resources, health and
environmental protection.
• Electronic direct-reading meter with high-definition LCD display can reads and sends digital information directly.
• High
sensitivity electronic meter with low starting flow measurement, high
precision measurement and automatic error correction function.
• Low power consumption, normal working can be power supplied by M-BUS /RS 485 communication ports line.
• Measuring maintains for 5 years power supplied by backup internal battery when communication ports line is broken.
• Permanent data storage
• The internal real time clock can be proofread by upper computer.
• Remote control implemented when installs a valve in the meter.
• Communication ports: M-BUS/RS485
• Wire: two-core twisted-pair wire, no polarity connection
• Communications protocol: 《CJ/T188-2004》or《DL/T645-1997》or consulted
• At low zone is ± 5% from minimum flow rate (qmin) to transitional flow rate (qt) (exclusive boundary)
• At high zone is ± 2% from transitional flow rate (qt) to overload flow rate (qs)
