Atrato Atrato Series Ultrasonic Flow Meter 0.03L/min to 5L/min, 1/4 in BSP, NPT, 316 Stainless Steel Body, Model 74P-VQB-O-RS

Atrato 74P-VQB-O-RS ultrasonic flow meter is engineered for demanding industrial and process automation environments requiring precise liquid flow monitoring. Its robust 316 stainless steel body and PEEK wetted materials ensure excellent durability and chemical resistance. The unit supports flow rates from 0.03L/min up to 5L/min, delivering reliable measurements with an accuracy of ±1% across the entire range. The sealed electronics conform to an IP65 protection rating, enabling operation in harsh conditions.

The meter features a 1/4 inch connection thread size compatible with both BSP and NPT standards, allowing flexible installation options in piping systems. It withstands maximum operating temperatures of up to 65°C and pressure ratings as high as 20 bar, suitable for varied industrial applications.

Utilizing ultrasonic flow technology with no mechanical moving parts, this Flow Meter minimizes maintenance needs and increases operational life. The device offers two multi-coloured LEDs for easy flow indication and provides NPN and PNP pulse outputs for seamless integration with control systems.

This model is ideal for use in water treatment plants, chemical processing, manufacturing facilities, HVAC systems, and laboratory setups where accurate, real-time flow data is critical. The meter’s high turndown ratio facilitates effective measurement over a wide range of flow conditions.

Key wetted parts consist of PEEK and stainless steel to ensure chemical inertness and mechanical strength. The product is manufactured in the United Kingdom, assuring quality and durability.
