Ultrasonic transit-time flow meter US W02

volumefor liquidsDN25 - 1"

Overview
Wear- and maintenance-free ultrasonic measurement enables high-accuracy flow measurement independent of fluid conductivity. The meter is extendable with optional temperature and pressure sensors and can be integrated into sensor networks via JUMO digiLine or IO-Link. Configuration is fast via Bluetooth and the mobile app; RS485 and Digital Sensor Management software are available for additional integration.

Highlights

• Independent of fluid conductivity
• High precision: 1 % of measured value
• Expandable with temperature and pressure sensors
