Ultrasonic clamp-on flowmeter for temporary flow measurement of liquids

  • Portable, battery-powered meter used to collect additional flow data or for cost-effective on-site verification of inline flowmeters
  • For pipes DN15…4000 / ½…160"; up to +120°C / +248°F
  • Portable signal converter with integrated data logger
  • Commissioning, monitoring and data analysis via a mobile smart device using the OPTISONIC 6300 P mobile app in combination with a USB cable or wireless Bluetooth connection®

OPTISONIC 6300 P with tablet – Version for V-mode measurement on pipe sizes up to DN250 / 10”

OPTISONIC 6300 P DN50 V-mode with tablet

The OPTISONIC 6300 P is a portable, battery-powered ultrasonic clamp-on flowmeter for temporary flow measurement of (non-)conductive liquids in virtually all industries. It can be used at virtually any location without interrupting the process or cutting pipes. Due to its flexibility, the flowmeter is equally suited for comparative measurements on stationary measuring equipment (e.g. pumps, flowmeters etc.) or for use as a short-term replacement of faulty devices. The clamp-on flowmeter comes with a measurement option for thermal energy applications as standard.

The OPTISONIC 6300 P combines robust, easy-to-mount clamp-on sensor rails with a battery-powered signal converter for 1 or 2 path measurement. The portable converter comes with full measurement functionality and an integrated data logger. All measurement data can be monitored and analysed via a smart handheld or mobile device using the OPTISONIC 6300 P mobile app. The Android app is free and makes it easy to set up and commission the clamp-on flowmeter. A user-friendly installation wizard guides the user through the configuration process. A USB cable or secure wireless Bluetooth® connection transfers data between the smart device and signal converter. All data is saved on the mobile device and can be evaluated.
