1. What IsTF1100-DC Wall Mounted Dual Channels Ultrasonic Flow Meter?
The TF1100-DC Wall Mounted Dual Channels Ultrasonic Flow Meter is designed for non-invasive flow measurement in fully filled pipelines. Using ultrasonic transit-time technology, it measures liquid flow through clamp-on transducers installed outside the pipe, without cutting the pipeline or interrupting the process.
With its dual-channel design, flexible transducer options, and multiple output interfaces, the TF1100-DC is suitable for industrial flow monitoring, pipeline inspection, and equipment performance evaluation.
2. How Does the TF1100-DC Ultrasonic Flow Meter Work?
The TF1100-DC operates on the ultrasonic transit-time difference principle. Ultrasonic transducers transmit and receive signals traveling upstream and downstream through the flowing liquid.
The downstream signal travels faster relative to the liquid, while the upstream signal travels slower. The difference in transit time is used to calculate flow velocity and volumetric flow rate.
As the transducers are mounted outside the pipe, the instrument provides non-invasive measurement without direct contact between the sensors and the liquid.
3. What Are the Key Features of the TF1100-DC?
4. What Are the Technical Specifications of the TF1100-DC?
The product page lists a pipe diameter range of 20 mm to 6.0 m. Detailed specifications list Type A transducers for 40–4000 mm and Type B for 20–50 mm. Confirm the applicable range with Lanrui Instruments before ordering.
5. Where Can the TF1100-DC Be Used?
The TF1100-DC is suitable for flow monitoring and maintenance across various industries:
Chemical and petrochemical industries
HVAC systems
Power generation
Food and beverage industries
Metallurgy and mining
Mechanical and plant engineering
Application suitability depends on the liquid properties, pipe conditions, and selected transducers.
Dual-channel design
Supports flexible measurement configurations using compatible transducers.
Clamp-on installation
No pipe cutting is required for normal sensor installation.
Wide pipe diameter coverage
Different transducer options accommodate various pipe sizes.
Bidirectional measurement
Measures flow in both directions.
Data logging
Records measurement data for monitoring and analysis.
Multiple outputs
Supports 4–20 mA, OCT, relay, and RS485 Modbus, depending on configuration.
Optional thermal energy measurement
Compatible PT1000 temperature sensors enable thermal energy applications.
6. How Should the TF1100-DC Be Installed?
Weak signal strength is one of the most common troubleshooting concerns when installing a clamp-on ultrasonic flow meter. If the TF1100-DC displays a weak signal or unstable flow readings, check the following items in order:
1Verify pipe parameters
Confirm the outside diameter, wall thickness, pipe material and liner information.
2Check transducer spacing
Make sure the actual sensor distance matches the value calculated by the instrument.
3Inspect the mounting surface
Remove loose rust, dirt, excessive paint or other surface irregularities.
4Check acoustic coupling
Apply the recommended coupling compound and make sure both sensors are firmly mounted.
5Confirm the pipe is full
Air pockets or a partially filled pipeline can disrupt the acoustic path.
6Examine the liquid
High concentrations of gas bubbles or solids may make transit-time measurement unsuitable.
7Review the installation location
Move the sensors away from pumps, elbows, valves and other sources of flow disturbance.
A systematic installation check is usually more effective than repeatedly changing instrument settings without identifying the underlying cause.
7. Where Can the TF1100-DC Be Used?
The TF1100-DC combines non-invasive installation with flexible measurement capabilities.
Easy installation: No need to cut the pipe for normal clamp-on installation.
Reduced maintenance: No wetted moving parts to experience mechanical wear.
Flexible monitoring: Dual-channel capability and bidirectional measurement support different requirements.
System integration: Multiple output options allow connection to compatible monitoring and control systems.
Energy monitoring: Optional PT1000 sensors support thermal energy measurement.
These features make the TF1100-DC a practical solution for industrial flow monitoring, maintenance, and process optimization.
FAQ
