Utilize Everywhere
Any Application, Any Liquid, Any Location
The FD-X Series is versatile, suitable for a wide range of applications, liquids, and locations.
Applications:
Spraying/Coating
Easily monitor for clogs in spraying lines and ensure the proper amount of liquid has been applied.
- Flow of Release Agent for Molds/Dies: Ensure that release agents are properly being applied to prevent mold or die damage.
- Coating Spray Amount Confirmation: Verify that a consistent amount of coating material is applied uniformly across components.
Filling/Injecting
Ensure the appropriate amount of liquid has passed through the system.
- Proper Chemical Mixing: Reliable monitoring of mixing fluids is necessary to ensure that appropriate liquid balances are met.
- Product Filling: Verify the correct amount of product has been added to a package or container.
Dispensing
Confirm that the proper amount of liquid is being dispensed or applied when necessary.
- Sealant Dispensing: Monitor the flow of sealant material (e.g., FIPG) to prevent potentially harmful gaps in material.
- Specialized Liquid Application: Precise application of specialized liquids (e.g., flux, adhesives, chemicals, etc.) can be confirmed to ensure proper assembly.
Cooling/Lubricating
Monitor cooling and lubricating lines to prevent overheating or damage.
- Chiller Flow Confirmation: Prevent costly overheating by monitoring all cooling lines individually to catch potential concerns.
- Part Lubrication Monitoring: Ensure a steady flow of lubricant or oil on all parts to prevent machine damage, even in harsh environments.
Any Liquid
The FD-X Series provides stable detection of all liquids, including those that are highly viscous (e.g., grease, adhesives, etc.), due to its high power.
- Viscous Liquids
- Corrosive Liquids: The non-contact detection method allows for corrosive liquids to be easily monitored without the fear of damaging the unit.
- Sanitary Liquids: The risk of contamination is eliminated because no process modifications are necessary and the sensor does not touch the liquid.
Compatible liquids include: Water, Grease, Oil/Lubricant, Adhesive, Chemicals, FIPG.
Any Tube/Pipe
The FD-X Series is compatible with metal pipes, plastic tubes, and uniform rubber hosing. These sensors will be able to easily Clamp-On pipes/tubes ranging from 3 mm to 14 mm (0.12" to 0.55").
- Plastic/Rubber Pipes: Ø3-12 mm (0.12"-0.47")
- Metal Pipes: Ø3-14 mm (0.12"-0.55")
Any Space
The impressively small FD-X Series heads are approximately 1/10 the size of a conventional Coriolis Flow Meter. This allows the FD-X Series to be used in tight spaces and on multiple lines in close proximity.
Any Environment
The superior environmental resistance of the FD-X Series allows it to be exposed to water, oil, and chemicals without damage. The resin models feature a Carbon Fiber Reinforced Body for high chemical resistance, particularly useful in the semiconductor industry.
Ratings: IP68G, Chemical Resistant.
Hassle-Free Design
The clamp-on design ensures a hassle-free installation and operation.
Zero Impact on Process
- Clamp Directly on the Pipe/Tube: The Clamp-On design fits securely around the pipe or tube, without any impedance of flow. Simply Clamp-On and begin monitoring.
- No Clogging: Unlike conventional mechanical type flow sensors, the FD-X Series will not clog, as there is no physical contact with the liquid.
- No Pressure Loss: Maintaining proper pressure is key in micro flow applications. That is why the FD-X Series is specially designed to prevent any pressure loss.
No Pipe Modification Necessary
The elimination of the time and money associated with system modifications, machine downtime, and the purchasing of additional components, make the FD-X Series a viable solution in any situation.
No Special Tools Required
Installation requires zero specialized knowledge or tools. Both models simply require a Phillips-head screwdriver to securely install the FD-X Series in seconds.
No Maintenance
Since the FD-X Series does not come in contact with the liquid, the need for maintenance is virtually eliminated. This is unlike mechanical and coriolis type meters, which are prone to clogging or damage and consistently require maintenance.
Cost Comparison: The FD-X Series offers a Total Cost Reduction compared to conventional flow sensors/meters due to its design and minimal maintenance requirements.
Unmatched Detection
Micro Flow Detection
From a drop of water to a small spray of coating material, the FD-X Series is designed to detect some of the lowest flows imaginable with industry-leading reliability.
Impressive Repeatability
Depending on the model and pipe material, the FD-X Series is able to achieve a repeatability of ±0.1% of F.S. when monitoring instantaneous flow and ±0.003 mL when monitoring shot amounts.
| Instantaneous flow | Shot amount | |
|---|---|---|
| Plastic piping/tubing | ±0.1% of F.S. | ±0.003 mL |
| Metal piping | ±0.3% of F.S. | ±0.008 mL |
High-Speed Monitoring
The FD-X Series offers one of the industries fastest response times at 50 ms. This is achieved through the use of an innovative triple-core parallel processor and other advanced circuit design techniques.
Expansive Connectivity

Operating Principles
Delta TOF (Time of Flight)
Conventional ultrasonic flow sensors monitor flow by measuring the time it takes for an ultrasonic pulse to travel from a transmitting element to a receiving element. As the flow rate increases, the signal is accelerated and the transmission time decreases. This transmission time can then be directly correlated to the instantaneous flow rate. The FD-X Series improves upon this method by simultaneously monitoring two signals (one moving in the direction of flow and one moving against the direction of flow). By doing this, the readings remain consistent and stable regardless of external factors such as clogging or temperature changes.
- Basic Principle: The duration of the pulse is easily influenced by external factors.
- Delta TOF: External factors do not affect detection as the time difference between signals A and B remains the same.
Automatic Power Control
The stable transmission of the ultrasonic signal is imperative for consistent and reliable detection. To ensure stability on a large variety of pipe material, the FD-X Series utilizes an Automatic Power Control function, which identifies signal strengths and adjusts accordingly. This ensures stable detection on everything from steel pipes to rubber hoses.
Accumulated Signal Processing
By utilizing a unique signal processing methodology, the FD-X Series bases its detection on not just one signal transmission but multiple signal transmissions. This allows the unit to combine signals and completely ignore any external noise.
Guided Wave Technology
The effects of noise generated by the ultrasonic detection signal can be detrimental to stable detection. To prevent this, the FD-X Series has adopted several innovative noise reducing techniques, including guided wave technology, which prevents the signal from wrapping around the pipe and hampering detection.
