Product News
Micronics continues to innovate within the portable instrumentation market, focusing on the PF220B’s ease of use for field technicians. Recent updates have emphasized improved signal processing algorithms, which allow the meter to maintain accuracy even in environments with higher levels of pipe vibration or minor fluid aeration. The unit remains a global industry standard for rapid, non-invasive pipe auditing.
Operation & Usage Instructions
-
Surface Prep: Clean the pipe surface thoroughly. Remove paint, rust, or loose scale to ensure direct acoustic contact.
-
Coupling: Apply a generous amount of acoustic coupling grease to the sensors before strapping them to the pipe.
-
Sensor Spacing: Input the exact pipe material, diameter, and wall thickness into the PF220B menu. The unit will calculate the precise separation distance required for the sensors.
-
Mounting: Secure the transducers firmly using the provided mounting straps, ensuring they are aligned on the pipe’s horizontal axis.
-
Verification: Monitor the signal strength indicator on the LCD. A stable signal confirms proper sensor placement and coupling.
Product Operation
The flow meter operates by transmitting ultrasonic pulses through the pipe wall and into the fluid. One transducer acts as a transmitter and the other as a receiver. The “Transit-Time” principle measures the time difference between pulses traveling with the flow and against the flow. Because the fluid velocity affects the transit time, the PF220B microprocessor can accurately calculate the volumetric flow rate, displaying real-time data on the digital interface.
Q&A
Q: Can the PF220B measure flow through any pipe material?
A: It works on most common industrial materials such as steel, stainless steel, copper, PVC, and HDPE, provided the pipe wall is homogeneous and not overly corroded.
Q: Do I need to shut down the system to install the sensors?
A: No. A primary benefit of the PF220B is that it is fully non-invasive, allowing for measurement during full system operation.
Q: How do I calibrate the meter for different fluids?
A: The meter features a built-in library of common liquids. For specialized fluids, you can manually input the sonic velocity of the fluid to maintain high accuracy.
