Endress+Hauser Teqwave T Portable Ultrasonic Concentration Meter
The Endress+Hauser Teqwave T is a portable ultrasonic concentration meter designed for flexible, temporary in-situ liquid analysis in industrial plants and laboratories. Unlike fixed concentration measurement systems, Teqwave T can be moved between different measuring points, allowing one instrument to monitor liquid concentration at multiple locations.
The system combines a robust insertion sensor with a portable battery-powered transmitter, providing real-time concentration measurement without requiring continuous external power or routine laboratory sampling.
Portable and Mobile Concentration Measurement
A key advantage of the Teqwave T is its mobile design.
One device can be used at different measuring points throughout a plant or laboratory. This makes it particularly useful when concentration measurement is required at changing locations rather than at a permanently installed measurement point.
Typical applications include:
Temporary liquid concentration measurement
Multiple-point process monitoring
Laboratory liquid analysis
Production line monitoring
Product quality inspection
Process troubleshooting
Concentration verification
Cleaning and surface-treatment processes
Real-Time In-Situ Liquid Analysis
Teqwave T performs real-time in-situ liquid concentration measurement, allowing operators to obtain process information directly from the liquid without repeatedly taking samples for laboratory analysis.
This can help reduce sampling requirements and provide faster feedback when monitoring concentration-dependent processes.
The system is particularly useful when operators need to quickly check concentration at different locations throughout a production process.
Ultrasonic Concentration Measurement
The Teqwave T uses surface acoustic wave technology for ultrasonic concentration measurement.
Its acoustic waveguide is designed to detect even small changes in the acoustic properties of the liquid, enabling precise monitoring of concentration and related liquid parameters.
The maximum concentration measurement range is:
0 to 100%, depending on the selected concentration application and application data.
Multivariable Liquid Measurement
In addition to concentration, Teqwave T can provide information about several liquid properties:
Concentration
Temperature
Sound velocity
Acoustic density
Dispersion
The specified measurement ranges include:
Sound velocity: 600–2000 m/s
Temperature: 0–100 °C
Acoustic density: 0.7–1.5 g/cm³
This provides additional information about liquid characteristics and supports more comprehensive process analysis.
180 mm Insertion Sensor
The Teqwave T uses an insertion sensor with an insertion length of:
180 mm (7 in).
The sensor is designed for accurate measurement independent of the flow profile, which provides flexibility when checking liquids at different process locations.
The sensor uses 1.4571 (316 Ti) stainless steel wetted material, supporting reliable use in industrial liquid analysis applications.
Battery-Powered Portable Transmitter
The Teqwave T transmitter is equipped with a:
2300 mAh Li-ion battery
and provides up to:
8 hours of mobile operation without external power.
This battery-powered design is one of the main differences between Teqwave T and permanently installed Teqwave concentration meters.
It allows operators to take the instrument directly to the required measurement location without having to install a dedicated power supply.
Large Color Display
The portable transmitter features a:
3.5-inch TFT color display with 4 operating keys.
The display provides clear access to measurement information and device status during mobile operation.
The straightforward operating concept allows operators to perform measurements without requiring extensive metrology knowledge.
Pre-Configured Measuring Points
Teqwave T supports pre-configured measuring points, allowing the instrument to be quickly matched to different measurement locations within a plant.
This is particularly useful when a production facility needs to check concentration at several predefined locations using the same portable measuring device.
Integrated Data Storage
The portable transmitter can store up to:
3,000 measured values.
This allows measurement results to be retained for later review and comparison, supporting process monitoring, quality control and troubleshooting.
No Sampling Required
Teqwave T provides an alternative to conventional manual sampling and laboratory analysis.
Instead of collecting samples and transporting them to a laboratory, operators can take the portable instrument directly to the process and obtain concentration information in situ.
This can help:
Reduce sampling work
Speed up concentration checks
Improve process visibility
Reduce laboratory workload
Support faster process decisions
Monitor product quality more efficiently
Robust and Maintenance-Free Sensor
The sensor is designed as a robust, maintenance-free ultrasonic measuring device, supporting reliable temporary measurements in industrial environments.
The sensor has an IP68 protection rating when the cable is plugged in, while the portable transmitter is rated IP65.
Wide Liquid Temperature Range
Teqwave T supports liquid temperatures from:
0 to +100 °C (32 to +212 °F).
This allows the portable concentration meter to be used across a wide range of industrial liquid analysis applications.
Typical Applications
The Endress+Hauser Teqwave T is suitable for:
Temporary liquid concentration measurement
In-situ liquid analysis
Portable concentration measurement
Multiple-point concentration monitoring
Laboratory liquid analysis
Industrial process monitoring
Product quality monitoring
Cleaning solution monitoring
Degreasing solution monitoring
Surface treatment processes
Concentration verification
Process troubleshooting
Mobile plant inspection
Endress+Hauser specifically documents applications involving passivation and degreasing solutions in surface treatment, demonstrating the suitability of Teqwave T for chemical concentration monitoring in industrial production processes.
