Product Details
Description:
USM-RA/RS Series Ultrasonic Gas Meter is a type of electronic
meter that adopts TOF (Time of Speed) principle to measure flow
velocity of gas medium. Employing advanced ultrasonic technology,
this meter ensures high-precision, wear-free gas flow
measurement, providing accurate and reliable results over time.
With Cubic's advanced algorithm technology, the Cubic ultrasonic
gas meter offers excellent adaptability to real gas conditions
and can accurately measure natural gas, natural gas with 23%
hydrogen (H₂), and LPG.
USM-RA/RS Series integrates seamlessly with GPRS, NB-IoT, and
other IoT technologies, facilitating real-time remote monitoring
and management. This allows users to effortlessly track gas
consumption and monitor the meter's status from anywhere.
Both steel and aluminum case options are available for the gas
meter.
Designed to operate effectively in extreme conditions, the
USM-RS-L series performs reliably across a wide temperature range
from -40℃ to +60℃, making it suitable for even the harsh
environments.
With class 1.5 accuracy and Compliant with MID and OIML, this
meter is suited for residential applications in the global
market.
Features:
- Long-time Accuracy: Ultrasonic technology features no
mechanical wear, ensuring no accuracy degrade over long-term
usage and no magnetic field effects.
- Good Gas Sources Adaptability: Various real-gas test and
intelligent software algorithm ensure compatibility with
different gas sources.
- Low Pressure Loss & Maintenance-free: With no moving parts,
the meter offers minimal obstruction to gas flow and eliminates
wear and tear, requiring no maintenance.
- Real-time Temperature Correction: Temperature correction is
standard, and pressure correction can be configurable.
- Anti-contamination & High Corrosion Resistance: Unique
hardware ensures reliable performance in dusty gas and corrosion
resistance, while optimized software maintains accurate signals
in dust-filled gas.
- Low Power Consumption: Both hardware and software patent
design ensure ultra-low power consumption, enabling a battery
lifespan of over 10 years.
- Integrated Remote Transmission Modules: Built-in GPRS and
NB-IoT modules allow real-time gas consumption monitoring and
meter status management.
- Instant Alarms for Easy Service: Alerts are triggered for
tampering attempts, low battery levels, and battery removal,
ensuring timely service.
- Strong Expandability: The fully electronic design supports
easy expansion for additional functions such as remote charging,
valve control, and various alarms.
