d. Mechanical Water Meter Series

Under the measurement conditions, continuous flow, memory and display of the total amount of cold (hot) water flowing through the enclosed full pipe.

Performance Characteristics
• Metering structure: single stream or multi-stream structure is adopted
• Wet type movement: high sensitivity; special liquid encapsulation of the character wheel window can keep the reading clear for a long time
• Dry-type movement : magnetic transmission in the center of the movement, anti-magnetic interference, good stability, strong structure anti-freezing ability, clear reading
• Optional materials: ductile iron, engineering plastics, copper, stainless steel
• Temperature class: T30, T90
• Accuracy Class: Class 2

e. Bulk Water Meter Series

Under the measurement conditions, continuous flow, memory and display of the total amount of cold (hot) water flowing through the enclosed full pipe

Performance Characteristics
• The counter is vacuum-sealed to prevent condensation and atomization, which can keep reading clearly for a long time
• Stainless steel ball rolling ball bearings, with less friction, improve measurement sensitivity and ensure accurate measurement of small flows
• With a detachable movement structure, the water meter movement can be removed or repair or replacement at the use site
• Sampling mode is optional: pulse, photoelectric
• Optional communication methods: wireless LoRa or NB-IOT, GPRS, wired RS-485 or M-BUS
• Environmental level: Class B electromagnetic environment: E1
• Temperature Class: T30, T90
• Accuracy Class: Class II
• Optional: Pressure sensor

f. Ultrasonic Meter Series

Ultrasonic remote water meter is composed of flow sensor and microprocessor, and adopts advanced ultrasonic measurement technology to measure the flow of water flowing through the pipeline. It can communicate with other devices through wireless or M-BUS interface to form a remote meter reading management system. The management department can overtake the data in the meter at any time to facilitate the management of user water consumption

Performance Characteristics
• Using ultrasonic measurement technology
• Without any mechanical transmission parts, the starting flow is low, and it is not affected by bad water quality
• High measurement accuracy and good stability
• It can measure heat and cold quantity
• Installation method: horizontal or vertical
• Environmental level: Class B electromagnetic environment: E1
• Temperature Class: T30, T90
• Accuracy Class: Class II
