Bonvoisin Handheld Ultrasonic Flow Meter Sourcing Portable Transit-Time Pipe Kits

Quick Answer: A Bonvoisin handheld ultrasonic flow meter kit uses clamp-on transit-time sensors for temporary or spot-check flow measurement on pipes from DN15 to DN6000. Silver Instruments supplies these portable kits for water, wastewater, oil, gas, and chemical plants. Share your pipe size, fluid, and flow range to get a quote with transducer selection.

What Is the Bonvoisin Handheld Ultrasonic Flow Meter Kit

This is a portable flow meter that clamps onto the outside of a pipe. No pipe cutting is needed. The transit-time method sends ultrasonic signals between two sensors. The meter calculates flow velocity from the signal time difference. Most kits include a handheld display, two clamp-on transducers, coupling gel, and a carrying case.

This meter is often used for field verification, pump testing, or checking an installed meter. We have seen customers use it for temporary flow surveys in water networks and cooling water lines. Because installation takes only a few minutes, it is a practical tool for maintenance teams.

Pipe Sizes and Fluid Conditions

The standard transducer sets cover DN15 to DN6000. Small pipes from DN15 to DN100 need small sensors. Medium pipes from DN50 to DN700 use medium sensors. Large pipes from DN300 to DN6000 require large sensors. The selection depends on pipe material and wall thickness. Common supported materials include carbon steel, stainless steel, PVC, copper, and cast iron.

The liquid should be relatively clean and contain less than 10,000 ppm suspended solids. Entrained gas above 2 percent volume can affect accuracy. Temperature range for standard transducers is typically 0 to 160 degrees Celsius. For higher temperatures, Silver Instruments can source high-temperature transducer kits.

Applications and Real Site Examples

Water and wastewater plants use this kit to check pump performance. Oil and gas teams use it to verify flow balance on cooling water and produced water lines. Chemical plants use it for dosing line checks. Food and beverage plants use it for CIP return lines and water audits. A desalination plant in Oman used this kit to verify brine flow during a shutdown.

In practice, many engineers buy this type of meter because it is quick to install. Last year a customer in Vietnam used one kit to test cooling water flow across a new production line. The readings matched their installed electromagnetic flow meter within 2 percent. Another customer, a paint manufacturer in Southeast Asia, used it to check solvent flow without stopping production. Most engineers skip this part during planning and later order the kit after a flow balance problem appears.

Technical Parameters That Matter for Procurement

When you request a quote, include these details. Pipe diameter in DN, pipe material, wall thickness, fluid type, temperature, pressure, and expected flow range. The standard handheld display supports velo

city range 0.01 to 12 m/s. Accuracy is typically plus or minus 1 percent of reading for pipe sizes above DN50. Repeatability is around 0.2 percent. The display runs on rechargeable batteries and lasts about 10 hours on a full charge.

Data logging can store around 30,000 data points on some models. Output options include 4-20 mA, RS485, and USB. Some kits include a wall thickness gauge or a PT100 temperature sensor for heat metering. Not all Bonvoisin kits include the same accessories, so verify the packing list with Silver Instruments before ordering. Here is the thing. The sensor set matters more than the display. A wrong sensor size on a thin-wall pipe will give unstable readings.

Sourcing from Silver Instruments

FAQ

Can this meter measure wastewater? It can measure wastewater if the liquid is not heavily loaded with solids or gas. For raw sewage with high solids or gas, a Doppler ultrasonic flow meter is a better choice.

Do I need to cut the pipe for installation? No. The sensors clamp onto the outside of the pipe. No pipe cutting or process shutdown is needed.

What accuracy can I expect? For pipes above DN50 with clean water and a stable flow profile, accuracy is about plus or minus 1 percent of reading. Small pipes or short straight runs can reduce accuracy.

Can this meter measure hot water or steam? It can measure hot water up to the transducer temperature limit, usually 160 degrees Celsius. It is not suitable for steam because the transit-time method needs a continuous liquid with no gas phase.

How do I get a price for a Bonvoisin handheld kit? Send your pipe size, fluid, temperature, and flow range to Silver Instruments by phone or WhatsApp. We reply with a quotation and shipping option within one business day.
