Ultrasonic Flow Meters

20+ Years Manufacturing Experience

WieTech 2025

From June 3 to June 5, 2025, Lanry Instruments (Shanghai) Co., Ltd. made a grand appearance at the Wietech 2025 exhibition held at the National Exhibition and Convention Center in Shanghai. As a significant event in the global environmental protection industry, Wietech 2025 attracted over 4,000 leading brands, with an expected attendance of more than 120,000 professional visitors across its expansive 260,000-square-meter exhibition space.

At this exhibition, Lanry Instruments showcased its cutting-edge products, including ultrasonic water meters, Doppler flow meters, and non-contact ultrasonic flow meters. The ultrasonic water meters, leveraging a dual-channel transit time ultrasonic measurement principle, feature zero moving parts and an ultra-wide turndown ratio (up to 500:1 for Q3:Q1), enabling bidirectional flow measurement. Constructed with SUS304 stainless steel, these meters offer a 15-year battery life and an IP68 protection rating, ensuring reliable operation even when submerged for extended periods.

Lanry’s Doppler flow meters are engineered for measuring flows in closed pipelines with media containing solid particles and bubbles. Utilizing an external non-contact sensor installation, these meters eliminate the need for pipeline shutdowns during setup, achieving a measurement accuracy of 0.5–2% FS while resisting interference from variable frequency drives.

Additionally, the portable Doppler ultrasonic open-channel flow meters, with an accuracy of 1% R, incorporate a 4.5-inch color LCD display. Capable of measuring both forward and reverse flow velocities, these devices support positive and negative cumulative calculations, making them ideal for applications in municipal underground pipe networks, wastewater treatment plants, and hydrological monitoring.

This participation not only spotlighted Lanry Instruments’ advanced flow measurement solutions but also fostered professional exchanges and collaborations. By doing so, the company further propelled the integration of flow measurement technologies in environmental protection, water management, and related sectors.
