Core Benefits of the Teqwave T D9TB

The E&H D9TB ultrasonic concentration meter delivers a combination of advantages that no benchtop instrument or inline-only sensor can match:

1. Real-Time, In Situ Liquid Analysis– Fast, efficient, and laboratory-grade accurate measurement without sample transportation or preparation delays. The acoustic waveguide measures precisely and reliably, detecting even the smallest concentration changes in real time-1-11.
2. One Device, Unlimited Measuring Points– A single D9TB portable ultrasonic concentration meter can monitor concentration values across dozens of locations throughout your plant. Pre-configured measuring points allow technicians to switch between applications without recalibration or specialized metrology knowledge-1-11.
3. No Flow Profile Interference– Unlike traditional flow-based measurement systems, the Teqwave T’s ultrasonic concentration technology delivers accurate readings completely independent of flow velocity and flow profile. This makes the D9TB ideal for temporary insertion into pipes, tanks, and vessels of virtually any configuration.
4. Maintenance-Free, Rugged Sensor– The stainless steel 1.4571 (316 Ti) sensor housing withstands harsh industrial environments. The robust sensor design eliminates moving parts and consumables, delivering reliable metering without scheduled maintenance-1-2.
5. Cost-Saving Quality Surveillance– Eliminate the need for routine grab sampling and off-site laboratory analysis. The D9TB-AAECCBCAAAAA1 enables continuous product quality surveillance directly at the point of use, dramatically reducing quality control turnaround time and associated costs-2.
6. Extended Mobile Operation– Powered by a 2300 mAh Li-ion battery, the portable transmitter supports up to 8 hours of continuous operation without external power. The integrated USB port enables convenient recharging between measurement campaigns-1-12.
7. Large Data Logging Capacity– Onboard storage accommodates up to 3000 measured values, allowing extended monitoring sessions without data loss. The integrated data storage is accessible via USB for post-processing and compliance documentation-1-2.
8. Intuitive Operation– The 3.5-inch TFT color display combined with four tactile operating keys provides straightforward navigation through pre-configured measuring points. No specialized metrology training is required for routine operation-12.

Application Fields

The E&H D9TB ultrasonic concentration meter has been successfully deployed across diverse industries:

Chemical Processing – Monitoring acid and caustic concentrations in cleaning baths, etching solutions, and neutralization processes. The D9TB-AAECCBCAAAAA1 has been validated for concentration measurement of deconex cleaning fluids in industrial parts cleaning applications–2.

Pharmaceutical & Biotech – Real-time concentration monitoring of fermentation broths, buffer solutions, and purification process intermediates. The portable design allows verification at multiple bioreactor ports without fixed inline sensors.

Metal Finishing & Surface Treatment – Concentration measurement of passivation baths, degreasing solutions, and plating electrolytes. Hug Oberflächentechnik GmbH successfully utilizes the Teqwave T for concentration monitoring of passivation and degreasing bath solutions-2.

Wastewater & Environmental – Monitoring industrial effluent concentrations, chemical dosing verification, and treatment process optimization.

Technology Deep Dive: How the D9TB Measures Concentration

The E&H D9TB Ultrasonic concentration meter employs Surface Acoustic Wave (SAW) technology, a sophisticated ultrasonic measurement principle that simultaneously captures multiple liquid properties:

The sensor emits ultrasonic signals through an acoustic waveguide. By analyzing signal transit time and amplitude attenuation, the device calculates three primary measurement variables: sound velocity (600–2000 m/s range), acoustic density (0.7–1.5 g/cm³), and temperature (0–100°C range)-1-11.

These measured variables are then processed through application-specific concentration algorithms. Endress+Hauser provides concentration application data sheets (concentration apps) calibrated for specific liquid pairs and concentration ranges. The concentration app approach enables exceptional accuracy – up to ±0.01% depending on the specific application – while maintaining the flexibility to reconfigure the D9TB-AAECCBCAAAAA1 for different measurement tasks-.

Understanding the D9TB Order Code Configuration

The complete product designation for the Teqwave T series follows a structured order code format. While the full configuration flexibility allows customization for specific application requirements, the D9TB-AAECCBCAAAAA1 represents a standard portable ultrasonic concentration meter configuration:
