Flow Meter Kit Packages: Portable Ultrasonic Flow Survey Toolcases for Engineers
Quick Answer: A portable ultrasonic flow survey toolcase lets you check liquid flow from outside the pipe without a shutdown. Silver Instruments supplies complete flow meter kit packages with clamp-on transducers, a handheld converter, coupling pads, mounting rails, a thickness gauge, and a hard case. Send your pipe size, fluid, temperature, pressure, and flow range for a quote.
What Is Inside the Toolcase
The standard Silver Instruments flow meter kit package includes a handheld ultrasonic converter, two clamp-on transducers, two steel mounting rails, coupling pads, an ultrasonic thickness gauge, a charger, a USB cable, a tape measure, and a hard copy setup guide.
The hard case has custom foam inserts and protects the parts on flights to remote plants or offshore platforms. The handheld converter runs for about 10 hours on one charge and stores up to 100,000 data points.
The converter supports 4-20 mA HART output, pulse output, and RS485 Modbus RTU. This lets you connect the survey kit to a plant control system for a temporary test.
Why Field Engineers Use Clamp-On Survey Kits
Because the transducers clamp onto the outside of the pipe, there is no hot work permit and no process shutdown. A field engineer can set up the meter in 10 to 15 minutes on a clean pipe run.
Here is the thing. Signal quality matters more than the meter brand. Internal scale, air bubbles, and loose sensor contact cause more failed surveys than the hardware itself.
These kits work best on clean liquids, water, wastewater with low solids, diesel, glycol, seawater, and light chemicals. Do not use the clamp-on meter on steam, gas, or heavy slurries.
Specific Customer Examples
A customer in Vietnam runs a chemical blending plant. He used the toolcase to check a DN80 cooling water line. The meter showed low signal because of internal scale. He moved the sensors to a cleaner section and the reading stabilized at 42.3 m3/h.
A paint manufacturer in Southeast Asia uses the same portable ultrasonic flow survey toolcase for quarterly energy audits. The team surveys chilled water lines at 12 points in one afternoon and finds fouled heat exchangers before production slows.
In practice, these kits work on any liquid line with straight pipe access. Common applications include desalination plants, mine dewatering, building HVAC circuits, and food plant clean-in-place lines.
Key Specifications to Confirm Before You Order
Pipe size matters first. Standard clamp-on sensors cover DN15 to DN6000. For pipes under DN25, use the small pipe transducers. For pipe walls over 30 mm thick, confirm the transducer frequency with our application team.
Fluid temperature range is -30 °C to 160 °C for standard sensors. Pressure does not affect the clamp-on measurement because the sensors sit outside the pipe. Accuracy is ±1.0 percent of reading for DN50 and above. For DN15 to DN40, accuracy is ±2.0 percent under good conditions. Repeatability is ±0.2
How to Run a Reliable Flow Survey
Pick a straight pipe section. Use at least 10 pipe diameters upstream of a bend and 5 pipe diameters downstream. For a DN100 pipe, that means 1000 mm straight before the sensor and 500 mm after the sensor.
Clean the pipe surface. Remove rust, paint flakes, and loose insulation. Apply coupling pads evenly between the transducer face and the pipe wall. Tighten the mounting rails until the sensor does not slide.
Enter the pipe outer diameter, wall thickness, material, and liner into the handheld converter. The meter calculates the sensor spacing. Most engineers skip this part. Measure the spacing with the tape measure. Small spacing errors change the reading more than most engineers expect.
Common Pipe and Fluid Conditions That Affect Accuracy
Internal scale on steel pipes reduces signal. Move the sensor to a cleaner section or use a thicker coupling pad. Air bubbles from pumps or partially filled pipes scatter the ultrasonic signal. Loose liners can also make the reading jump or fail. We have seen this on customer sites many times.

FAQ: Five Practical Questions
Can this portable ultrasonic flow meter kit measure wastewater?
Yes, if the wastewater has less than 3 percent solids and the pipe runs full. High solids and heavy foam reduce signal quality. For raw sewage, a clamp-on flow survey works best at the discharge side of a screen or after primary treatment.
What pipe materials work with the clamp-on transducers?
Carbon steel, stainless steel, cast iron, ductile iron, copper, PVC, HDPE, and PVDF work well. Concrete pipes and fiberglass pipes need application review because the wall transmits sound differently.
Do I need to shut down the line to install the kit?
No. The clamp-on sensors install on the outside of the pipe. The line keeps running at full pressure and full temperature during the survey. This is the main reason plants use this flow meter kit package.
What is the smallest pipe size this kit can measure?
The small pipe transducers cover DN15 to DN25. Measurement on small pipes needs careful sensor alignment and clean pipe surface. The accuracy is lower than on DN50 and larger pipes because the sound path is short.
Can the toolcase be shipped to another country?
Yes. Silver Instruments ships worldwide from Nanjing, China. The hard case meets normal air freight requirements for lithium battery equipment. We provide a commercial invoice and packing list for customs clearance.
