1. Introduction

Portable ultrasonic clamp-on flowmeter from Krohne. The perfect measuring device for temporary flow monitoring in numerous applications. Thanks to its mobility, the device is equally suited to comparative measurements on stationary measuring equipment or for use as a short-term replacement for faulty devices or even for quick liquid measurement with the proven precision and reliability of KROHNE ultrasonic technology.




We simply attach the sensor unit to the tube and connect the compact evaluation unit and read the results.

All it takes are a few simple moves and just a few minutes to complete installation. It is powered by the integrated battery (14 hours running time) or the mains adapter supplied. The readings are shown on the large colour LCD in a graphical format. The OPTISONIC 6300 P stores the readings in the integrated memory for data logging. They can then be transferred via USB stick to a PC.

RMS provide in the end of each visit a full report for the reading and
