Understanding the different types helps businesses select the right model for their specific fluid, pipe, and environmental conditions.

Ultrasonic Flow Meters

These are the foundational technology behind most Flexim devices. They operate by transmitting high-frequency ultrasonic signals through the pipe wall and into the fluid. By measuring the time difference between upstream and downstream signal travel, the meter calculates the average fluid velocity and derives the volumetric flow rate.

Advantages

• Non-invasive installation (clamp-on)
• No pressure drop or flow obstruction
• High accuracy (±0.5% to ±1%)
• Suitable for a wide range of pipe sizes
• Ideal for temporary or permanent monitoring

Limitations

• Requires clean, homogeneous fluids for best results
• Signal quality can be affected by pipe material or lining
• Higher initial cost compared to mechanical meters

Best for: Water, wastewater, chemicals, and HVAC systems where minimal maintenance and high reliability are critical.

Time-of-Flight (TOF) Flowmeters

Also known as transit-time meters, TOF flowmeters use two ultrasonic transducers mounted on opposite sides of the pipe. One sends a signal with the flow, the other against it. The time difference between the two signals is directly proportional to the fluid’s velocity. This method is highly accurate for clean liquids and gases.

Advantages

• Exceptional accuracy for clean fluids
• Bidirectional flow measurement
• Low maintenance with no moving parts
• Effective in large-diameter pipes
• Real-time digital output and diagnostics

Limitations

• Performance degrades with suspended solids or bubbles
• Requires a minimum fluid conductivity and homogeneity
• Installation alignment is critical

Best for: Potable water, oils, solvents, and compressed air systems where precision and long-term stability are essential.

Cross-Correlation Flowmeters

This advanced method uses two ultrasonic sensors placed at a known distance apart. It analyzes the time delay between similar flow "signatures" (natural turbulence or introduced markers) detected by each sensor. By correlating the signals, the system calculates the fluid’s velocity with high repeatability, even in challenging conditions.

Advantages

• Highly effective in turbulent or non-uniform flows
• Less sensitive to flow profile disturbances
• Works well in partially filled pipes
• Robust in varying fluid conditions

Limitations

• More complex signal processing required
• Higher cost due to advanced electronics
• May require calibration for specific applications

Best for: Wastewater, slurry transport, and industrial processes with fluctuating flow profiles.

Shallow Detection Flowmeters

Designed for applications where deep signal penetration is not possible or desirable. These meters use high-frequency ultrasonic pulses that travel a short distance through the pipe wall and fluid. The reflected signal is analyzed to determine flow velocity, making them ideal for thin-walled or lined pipes.

Advantages

• Effective on lined or coated pipes
• Minimal signal loss in thin materials
• Resistant to external noise and vibration
• Top-mounted transducers reduce sediment interference

Limitations

• Limited to smaller pipe diameters
• Less effective in highly attenuating fluids
• Requires precise sensor placement

Best for: Chemical processing, pharmaceutical lines, and lined pipelines where standard penetration would fail.

Doppler Flowmeters

Doppler flowmeters rely on the frequency shift of ultrasonic waves reflected by suspended particles or gas bubbles in the fluid. The difference between the transmitted and reflected frequency (Doppler shift) is used to calculate fluid velocity. This makes them uniquely suited for dirty or aerated liquids.

Advantages

• Excellent for slurries, wastewater, and aerated fluids
• Does not require clean, homogeneous flow
• Effective in high-solid-content applications
• Simple principle with reliable output in dirty conditions

Limitations

• Inaccurate in clean fluids (no reflectors)
• Measurement depends on particle concentration and size
• Lower accuracy compared to TOF meters (±2–5%)

Best for: Mining, sewage treatment, pulp and paper, and any application with particulate-laden fluids.
