The Ultraflux Minisonic II portable ultrasonic flow meter is a clamp-on flowmeter suitable for temporary flow measurements on all clean liquids like water or chemicals.
The Ultraflux Minisonic II Portable Ultrasonic Flow Meter is a reliable clamp-on flow meter for temporary liquid flow measurements. The Minisonic II portable flow meter is suitable for all clean liquids such as water, glycol mixture, or chemicals. The Minisonic II portable flowmeter is a non0invasive meter and does not require any pipe cutting.
The Minisonic II portable ultrasonic flow meter utilizes the transit-time technology to calculate the flow velocity and volumetric flow rate. The flow meter consists of two transducers that alternately send and receive ultrasonic signals to measure the transit time difference between the transmitted and received ultrasound signal. This difference in transit time is a direct measure of liquid flow rate. Learn more here.
Transit time flow meters are suitable to measure clean homogenous liquids that do not suffer from aeration or contain high concentration of suspended solids. This is because the ultrasonic signals will suffer from signal attenuation resulting in a poor flow reading.
If the liquid that you are measuring contains entrained gas or suspended solids at or above a concentration of 10% (by volume) then you might want to consider using our Compu-Flow Doppler Ultrasonic Flow Meter for your flow measurements.
Plant managers and maintenance technicians find our Minisonic II flowmeter to be a very user-friendly instrument because anyone can use it without requiring deep technical knowledge. You may carry out various maintenance activities using this portable flow meter such as:
HVAC Commissioning (water side): All HVAC systems (heating and cooling systems) require several checks during the commissioning stage before the final hand-over. The Ultraflux Minisonic II portable meter can help with primary and secondary pump output flow verification (GPM), network leak detection, bypass-valve control check, hydraulic balancing, and much more.
Flowmeter Verification: In-line flow meters such as turbine or electromagnetic flowmeters suffer from calibration drift over time due to several factors. This drift causes tremendous measurement errors, which affects the efficiency of your process or quality of the final product. The Minisonic II portable flow meter can be installed adjacent to your existing flowmeters for a quick accuracy check. This will help you ensure whether or not your flow meters are performing as per specified accuracy.
You now have the option to rent our flow meter to verify the accuracy of your flow meters. Or you may contact us for a meter verification service by an experienced engineer.
Fire Sprinkler System Inspection: All fire systems in commercial or residential buildings must meet local or city safety ordinances by law and require yearly or quarterly certified inspections of mechanical equipment to ensure safe operation during emergencies. The Minisonic II portable ultrasonic flow meter can be used to perform fire sprinkler inspections to certify that the pumps produce sufficient water flow (gpm or m3/h) and that the butterfly valves are performing as intended (no backflow).
Leak Detection: The Minisonic II flow meter is also an ideal mobile solution for water leak detection in network pipes. For instance, the flow meter can sense liquid velocities down to ±0.03 ft/s so even small movement in water at low-peak times can be precisely detected.
Network Metering: Water utility companies and district cooling plants have an extensive water pipe network (underground and above ground). During the design phase a lot of these pipelines are not provided with critical metering points that are required for proper measurement and control of the infrastructure. The Minisonic II flow meter can help operators carry out temporary flow measurements at various points in the network to study the feasibility of adding additional metering points.
The Minisonic II portable ultrasonic flow meter has a robust design for harsh environments and is rated IP68 for complete water and dust protection. With an internal datalogger, all your valuable measurement data is secure in its internal memory and ready for easy transfer to a computer for analysis and reporting.
