We has been providing a wide range of quality products, service and support to the application areas of superhard industry We fully integrate the resources of the superhard
Designed specifically for high-precision and highly reliable measurement in industrial and municipal water applications. Utilizing advanced ultrasonic transit-time difference technology with no moving mechanical parts, these meters eliminate the issues of accuracy degradation and shortened lifespan inherent in traditional mechanical meters due to wear and tear. Zhuozheng large diameter ultrasonic water meters are the ideal solution for smart water networks, District Metering Areas (DMAs), leakage control, and bulk water user billing.
1.High Accuracy:
Achieves ±1% high accuracy measurement across the entire flow range, maintaining excellent performance even at low flow rates, significantly improving metering efficiency and revenue protection.2.Wide Flow Range Ratio:
Features an extremely wide flow range ratio (high R value), enabling a single meter to accurately measure water flow from minimal trickle to maximum capacity.3.No Moving Parts, Zero Wear:
Ultrasonic measurement principle eliminates mechanical wear, requiring minimal maintenance and offering a significantly longer lifespan than traditional mechanical meters.4.Bidirectional Flow Measurement:
Accurately measures flow in both forward and reverse directions, suitable for scenarios requiring monitoring of backflow in pipelines.5.Excellent Low Flow Detection:
High sensitivity to detect minimal starting flow, effectively reducing under-registration of water consumption.6.Low Pressure Loss:
Straight-through measuring tube design offers minimal flow resistance, negligible impact on pipeline pressure, saving pumping energy.7.Multiple Data Interfaces & Communication Options:
Standard pulse output and RS485 interface (supporting protocols like Modbus). Optional wireless communication modules such as M-Bus, LoRaWAN, NB-IoT, 4G available for easy integration into Automatic Meter Reading (AMR) and smart water management systems.5.Data Logging & Alarm Functions:
Built-in data logger records historical data like total flow, instantaneous flow, forward/reverse flow; features alarms for empty pipe, malfunction, etc.6.Long Battery Life Design:
Utilizes high-performance lithium batteries, designed for a typical service life of 10+ years (depending on model and operating conditions).7.Robust Construction & High Protection Rating:
Robust housing and stable, reliable sensors. Typically rated IP68 for high ingress protection, suitable for harsh installation environments like underground pits or damp locations.8.Easy Installation, No Straight Pipe Requirements):
Compact inline design for easy installation. Some models require minimal upstream/downstream straight pipe lengths, offering great adaptability.)1.Industrial process monitoring (chemicals, pulp & paper)
