Overview

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 up to four measured values and thus reduces operational expenditure of a skid. Match your Teqwave transmitter perfectly to your production needs: You can individually define and extend your application range by use of the flexible app concept.

Benefits

  • Easy and efficient – real-time in situ liquid analysis

  • Full transparency – constant monitoring of product quality without sampling

  • Highest process safety – reliable metering due to robust, maintenance-free sensor

  • Cost-saving – fewer measuring points due to multivariable measurement

  • Customized usage – innovative app concept, easily expendable for changing measuring tasks

  • Simplified process control – user-friendly operation and clear status visualization

  • Local data backup – integrated data storage for measured values up to 7,5 years

Application

  • 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

  • Accurate and independent of flow profile

  • Insertion length: 180 mm (7") or 500 mm (20")

  • Industry-compliant, easy installation via DIN rail

  • 3.5" TFT color touch display or LED indication

  • 4-20 mA, Modbus TCP
