Fuji Portable Ultrasonic Flow Meter Kit: Conducting Quick Plant Surveys and Energy Management Audits
Quick Answer: A Fuji portable ultrasonic flow meter kit measures liquid flow from outside the pipe. You clamp the sensors on, read flow rate and totalizer data, and move to the next test point. This works well for quick plant surveys, pump audits, cooling water balance checks, and energy management baselines.
Plant engineers often find lines with no permanent flow meter. Cutting into a pipe costs money and takes time. A portable clamp-on ultrasonic flow meter solves this problem. We have seen this on customer sites in Southeast Asia, Australia, and the Middle East. One person can carry the kit and test multiple lines in a single shift.
What the Fuji Portable Ultrasonic Flow Meter Kit Includes
A typical kit includes a handheld transmitter, two clamp-on transducers, mounting rails, acoustic couplant, connection cables, a charger, and a hard carrying case. Some kits include a thickness gauge and a thermal printer. The transmitter stores logged data. You can transfer the data to a PC for audit reports. This data set supports a plant energy audit.
Most kits cover pipe sizes from DN13 to DN6000. The standard transducers handle temperatures from -40 °C to 120 °C depending on the supplier. High temperature transducers can go up to 200 °C. The meter accepts pipe materials like carbon steel, stainless steel, PVC, HDPE, and copper. These details matter when you select a sensor set.
Why Portable Clamp-On Surveys Beat Fixed Meters
In practice, fixed meters cost too much for temporary checks. You cannot install a permanent flow meter in every branch line. A portable kit gives you a repeatable measurement method. An engineer can test one line, log data for 30 minutes, then move to another line. This speed matters during a plant survey.
Most engineers skip the idea because they think ultrasonic meters are fragile. A good kit is not fragile. The transducers clamp on with rails or straps. The handheld unit has a clear signal quality display. If the signal is weak, you adjust the sensor spacing. That is the whole adjustment process.
How to Run a Quick Plant Survey with the Fuji Kit
First, record the pipe outer diameter and wall thickness. Clean the pipe surface. Apply couplant to the transducer face. Attach the sensors in V mode or Z mode. V mode works well on smaller pipes. Z mode works better on larger pipes above DN300. Enter the pipe material, wall thickness, fluid type, and sensor spacing into the handheld unit.
On a DN100 carbon steel cooling water line, a V mode setup with 2 MHz transducers often gives a stable signal within 2 minutes. Check the signal strength and sound speed. If the sound speed is off by more than 2 percent, check the couplant or sensor spacing. Log data for at least 10 minutes per point. Compare the totalizer with an existing plant meter if one is available. Then move to the next test point.
Energy Management Audits with Portable Ultrasonic Data
Energy audits require baseline flow data. You measure flow rate, fluid temperature, and running hours. Then you estimate pump energy, cooling load, or process heat balance. A Fuji portable ultrasonic flow meter kit works for water, glycol, light oils, diesel, and some chemicals. We have seen a paint manufacturer in Southeast Asia use this kit to find a bypass line that wasted chilled water. They fixed the bypass and saved roughly 11 percent on cooling energy in one month.
Do not try to measure steam or gas with a clamp-on liquid ultrasonic meter. That is a common mistake. For compressed air audits, use a thermal mass flow meter or a differential pressure fl
Recommended Models and Sensor Sizes
Silver Automation Instruments supplies portable clamp-on ultrasonic flow meters and can quote a Fuji portable ultrasonic flow meter kit for your audit. For most plant surveys, we recommend the Fuji Portaflow C or an equivalent clamp-on kit with two sets of transducers. Use small transducers for DN15 to DN100 pipes. Use medium transducers for DN50 to DN400 pipes. Large transducers cover DN300 to DN1500. Verify the pipe outer diameter before ordering.
A 50 mm pipe may need small or medium sensors depending on wall thickness and liner. A DN300 pipe with a thick cement liner may need a large transducer set. Tell us your pipe size, fluid, temperature, pressure, and expected flow range. We will confirm the right sensor and model.
Technical Parameters That Matter
Check these parameters before you buy. Pipe size range is the first filter. A kit that works from DN13 to DN6000 covers most plant lines. The second parameter is fluid temperature. Standard transducers handle up to 120 °C. High temperature sensors go up to 200 °C. The third parameter is pipe material and liner. Thick liners like cement or rubber weaken the acoustic signal.
The fourth parameter is flow velocity range. A typical portable ultrasonic meter reads from 0 to 12 m/s bidirectional. Accuracy is often 1 to 2 percent of reading for clean water with a fully developed flow profile. The transmitter logs data at 1 second or 5 second intervals. Use the logger for audit reports and before and after comparisons.
Common Applications in Different Industries
Water and wastewater plants use the kit to verify pump station flow. An operator can check a raw water intake line without shutdown. We have seen a dairy plant in Queensland use this kit to balance CIP return flow. A chemical terminal in Malaysia used it to confirm transfer flow between tanks. Marine engineers use portable ultrasonic meters to check engine cooling loops. Because the meter is portable, one unit covers many sites.
FAQ
Can this meter measure flow on a DN15 pipe?
Yes. Use the correct small transducers and check the pipe wall thickness. Below DN15 the signal becomes difficult. The flow profile may also be unstable.
Which fluids can a Fuji portable ultrasonic flow meter measure?
Clean liquids with low aeration or solids. Water, cooling water, glycol, light oils, diesel, and some chemicals work well. Slurries and liquids with bubbles reduce signal quality.
How long does one measurement point take?
On a clean DN100 steel pipe, setup and stable reading takes 5 to 15 minutes. Rough surfaces or thick liners need more surface preparation.
Do we need to cut the pipe or stop the process?
No. The sensors clamp on the outside. The process keeps running. This is the main reason plants use portable ultrasonic meters for energy audits.
What data should we send for a quote?
Pipe outer diameter, wall thickness, pipe material, fluid type, temperature, pressure, and expected flow range. Send these details to Silver Automation Instruments.
