The semi-liquid cover plate is clear and the corresponding components are vacuum treated and insulated from outside air and the measured water. This design minimizes atomization and helps keep the internal components clean and free. Key benefits - Improves reliability and accuracy by reducing evaporation and contamination of the sensitive parts - Reduces hydraulic losses while preserving performance through an enlarged inner cavity and optimized water flow paths - Enhances security and tamper resistance with built-in seals and a lead seal applied after rigorous factory testing - Delivers precise readings with a high sensitivity design and a combined digital and analog display Design and performance highlights - Clear semi-liquid cover plate with a vacuum-treated counterpart, insulated from external air and measured water to minimize vaporization and keep the system stable - Inner cavity is enlarged to reduce pressure loss; larger water inlet and outlet holes in the impeller box lower hydraulic resistance while maintaining overall performance - Seals are incorporated to prevent water theft; lead seal is applied after factory testing to ensure qualification, prevent tampering, and boost safety - High precision sensing: accuracy to 0.0001 with a combined display of numerical readout and hands for clear, quick interpretation Use scenarios - Residential or commercial water meters in homes, apartments, or small businesses where tamper resistance and high reading accuracy are important - Industrial facilities or large building complexes where reduced pressure loss improves flow efficiency and overall metering performance - Laboratories or healthcare facilities requiring secure, tamper-evident measurements and precise, easy-to-read data Compatibility and applicability - Designed to enhance standard metering setups with a focus on reliability, security, and precision - Suitable for installations where tamper resistance and minimal pressure loss contribute to operational efficiency and accurate billing Notes - All enhancements are implemented to preserve core measurement functions while delivering improved stability, security, and readability.
