Field of application
The insertion measuring device Teqwave I was developed for accurate real-time liquid analysis in vessels and larger pipes. Dedicated to in situ concentration measurement, Teqwave monitors various measuring parameters at once, and thus reduces operational expenditure. Match your Teqwave transmitter perfectly to your production needs: You can flexibly define and extend your application range.
- The acoustic waveguide measures precisely and reliably, even the smallest changes are detected 
- Continuous concentration measurement of liquids in vessels or large pipes. 
Device properties
- Insertion length: 180 mm (7 in) or 500 mm (20 in) 
- Accurate and independent of flow profile 
- Industry-compliant, easy installation via DIN rail 
- 3.5" TFT color touch screen or LED indication 
- 4-20 mA, Modbus TCP 
Benefits
- Easy and efficient – real-time in situ liquid analysis
