The T.S.P. Series-U is a high-precision, solid-state ultrasonic gas meter engineered to meet the evolving demands of modern energy grids. Developed by Tose'e Sanat Pouyagaran Ra'ad Danesh (T.S.P. Co.), this meter features advanced Time-of-Flight (ToF) sensing technology, providing exceptional metrological stability for both pure Natural Gas and Hydrogen-Natural Gas blends up to 20% (H2NG). By eliminating moving mechanical parts, the Series-U ensures zero drift over time, high immunity to contaminants, and a whisper-quiet operation suitable for residential and commercial environments.
Designed for the era of smart utilities, the T.S.P. Series-U integrates a dual-mode IoT communication module supporting LoRaWAN (Class A/C) and NB-IoT protocols. This robust connectivity ensures deep indoor penetration and reliable data transmission for Automatic Meter Reading (AMR) and Advanced Metering Infrastructure (AMI) systems. The device provides granular consumption data, flow rate analysis, and critical system health diagnostics directly to the utility provider, facilitating efficient load management and rapid leakage response.
Key Technical Specifications:
H2-Ready Measurement: Calibrated accuracy for Natural Gas mixtures containing 0% to 20% Hydrogen, compliant with future green energy distribution standards.
Advanced IoT Connectivity: Seamless integration via NB-IoT (Bands B3/B8/B20) and LoRaWAN (EU868/US915/AS923) for secure, long-range telemetry.
Solid-State Reliability: Non-intrusive ultrasonic sensors with no wear and tear, guaranteeing a service life exceeding 15 years.
Smart Diagnostics & Safety: Features integrated temperature and pressure compensation, tamper detection (magnetic/cover open), and an internal shut-off valve controllable remotely via the IoT network.
Ultra-Low Power Design: Optimized electronics architecture ensuring long-term battery autonomy in standard operating conditions.
This image showcases the high-capacity assembly and testing infrastructure of Tose'e Sanat Pouyagaran Ra'ad Danesh (T.S.P. Co.). Every Series-U Ultrasonic Gas Meter undergoes a meticulous manufacturing process, from precision electronics integration to automated flow-bench testing. Our facility is equipped with specialized pressure and flow calibration stations to verify metrological accuracy for hydrogen-enriched gas streams.
By combining skilled engineering with state-of-the-art diagnostic tools, we ensure that every IoT-enabled meter leaving our floor is field-ready for mission-critical utility applications.
The field installations of T.S.P. Series-U ultrasonic gas meters in residential complexes and multi-family apartments demonstrate a leap in urban energy management. Due to their compact, static design and the absence of bulky diaphragm mechanisms, these meters allow for organized, high-density bank installations within limited utility spaces.
Leveraging integrated LoRaWAN and NB-IoT communication protocols, the system enables fully automated remote meter reading, eliminating the need for manual onsite inspections and enhancing resident privacy.
Beyond smart connectivity, the Series-U maintains certified metrological precision for 20% Hydrogen-Natural Gas blends, ensuring long-term reliability and safety for the next generation of domestic energy infrastructure.
