Introduction

QT502 ultrasonic flow meter is a wall-mount, clamp-on or insertion type ultrasonic flow meter using transit-time technology. Both Clamp on type sensors and Insertion type sensors are available. New designed using advanced chip and low-voltage broadband pulse transmission, ensure flow meter with high accuracy and repeatability for long term operation.

Advantages

Comparing with other traditional flow meter, QT502 ultrasonic flow meter has distinctive features such as high precision, high reliability and high capability.
QT502 ultrasonic flow meter adopt user-friendly menu design. British and metric measurement units are available. Support to check total flow for the last 64days and months as well as for the last 6 years. With SD card function optional, ultrasonic flow meter could achieve data storage for analysis.

Application

QT502 ultrasonic flowmeter is widely applied in HVAC, water treatment, irrigation.
