Ultraflux portable flow meter is a robust IP68 ultrasonic flow meter for liquid flow testing. No pipe cutting. 100% leak proof. High accuracy.
The Ultraflux Uf 801-P Portable Flow Meter is a reliable solution for non-invasive flow measurements of liquids flowing in a closed pipe. The Uf 801 portable ultrasonic flow meter is suitable for all conductive and non-conductive liquids such as water, chemicals, toxic media, hydrocarbons, and more.
The Uf 801-P portable flow meter is installed externally on your process pipes, so it does not cause any leaks in your system. This creates a 100% non-invasive, non-intrusive metering solution that you can rely on for your process measurements.
The Uf801 flow meter utilizes transit-time ultrasonic technology (time-of-flight) 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 homogenous liquids that do not suffer from aeration and do not contain high concentration of suspended solids. Because, such particles in the liquid will behave as ultrasonic reflectors and cause 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 Uf 801-P portable flow meter 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. Our portable flow 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 Uf 801-P portable ultrasonic flowmeter can be installed adjacent to your existing flowmeters for a quick accuracy check. This will help you ensure your flow meters are performing as per specified accuracy.
You now have the option to rent our Uf 801-P portable ultrasonic flow meter to verify the accuracy of your flow meters. Or you may contact us for a meter verification service by an experienced engineer.
Energy Audits: The Uf 801-P flowmeter is equipped with two temperature inputs to measure supply and return temperatures in a heating or cooling system. The flow meter is supplied with a set of (optional) matched clamp-on temperature sensors, just like the flow transducers, to avoid pipe cutting. The flow meter provides energy consumption (BTU or kWh) using the temperature and flow measurements. The Uf 801-P is a great tool for ESCO’s (energy service companies) to perform energy audits to create an energy model of any facility.
Leak Detection: The Uf 801-P portable flowmeter is also an ideal portable metering solution for water leak detection in network pipes. For instance, the Uf 801-P 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 Uf 801-P portable flow meter can help the operators carry out temporary flow measurements at various points in the network to study the feasibility of adding additional metering points.
The Ultraflux Uf 801-P 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.
