Endress+Hauser Prosonic Flow Meter Setup for Non-Contact Fluid Tracking
Quick Answer: You can set up an Endress+Hauser Prosonic clamp-on flow meter for non-contact tracking by entering your pipe material, outer diameter, wall thickness, and fluid type into the transmitter. The sensor pair then mounts directly on the pipe exterior without process shutdown. Silver Instruments ships pre-configured Prosonic units and provides onsite startup support for water, chemical, and hydrocarbon flows.
Why Non-Contact Flow Tracking Matters
Many sites handle aggressive fluids like 98% sulfuric acid, sodium hypochlorite, or hot transfer oil. Cutting into a line to install an inline meter is risky and demands plant downtime. With an ultrasonic clamp-on meter from the Prosonic Flow W series, you avoid all wetted parts. The transducers strap onto the outside of the pipe. No flanges, no gaskets, no leak points. We often ship these units to water treatment plants in the Philippines, chemical dosing skids in Thailand, and diesel fuel lines in Nigeria. Because there is no pipe modification, plant engineers can install the meter in under two hours.
E+H Prosonic flow meters work with pipe sizes from DN15 up to DN4000. The latest Prosonic Flow W 400 transmitter runs with 4-20 mA HART, pulse, and Modbus outputs. It handles fluid temperatures from -40 °C to 130 °C, extendable to 200 °C with high-temperature sensors. Accuracy stays within ±1% of reading for clean liquids. Even fluids with a low sound speed, like hot crude oil at 120 °C, are measurable once you enter the correct sonic velocity into the parameter set.
Pre-Installation Checks Most Engineers Skip
Before you power on the transmitter, walk the pipe. Measure the outer diameter three times with a circumference tape, not once with a calliper. A DN100 Schedule 40 pipe has an exact OD of 114.3 mm, but if you measure 115 mm because of paint or rust, your flow reading will drift. Write down the wall thickness from the BOM or measure it with an ultrasonic thickness gauge. If the pipe has an internal liner (PTFE, rubber, glass), input the liner material and thickness. The Prosonic transmitter uses all these layers to compute the correct acoustic path.
In practice, a common mistake is ignoring the pipe condition. On old cast iron water mains in a desalination plant in Oman, we saw signal loss because of internal scale 2 mm thick. The fix was simple: enter an additional scale layer with estimated sound speed, or clean a small spot on the pipe exterior and increase the gel contact.

Step-by-Step Setup on the Transmitter
Here is the setup flow we follow when we commission a Prosonic 93W or W 400 for a customer. Power up the transmitter and select the "Clamp-on" sensor mode. The wizard asks for mounting type: V for small pipes (DN15-DN50), W for medium (DN50-DN200), and Z for large pipes (DN200+). Next come the pipe parameters: outer diameter in mm, pipe material (stainless steel 316L, carbon steel, PVC, HDPE), wall thickness in mm, and liner material if present. The database inside the transmitter already holds sound speed for common materials. Then select the fluid. For water, choose the water profile. For diesel, select "oil 2" or enter a custom sound speed if you have lab data. Enter the fluid operating temperature because sound velocity shifts roughly 3 m/s per °C in water.
After you confirm all inputs, the screen displays the sensor distance in mm. Mark that distance on the pipe with a pencil. Clean the areas with a wire brush
Most engineers skip the zero check on existing lines, but even a closed valve can leak a trickle flow. We always ask the operator to confirm the pipe is truly static during the zero step.
Applications Where Non-Contact Tracking Saves the Day
A paint manufacturer in Vietnam tracked xylene flow on a DN25 PVC pipe at 28 °C without any metallic wetted parts. The Prosonic 93W gave stable readings at 120 kg/h after they entered the correct PVC wall thickness of 2.0 mm. In Indonesia, a coffee processing plant used a clamp-on meter to measure condensed milk flow through a DN50 stainless tube. They had been unable to find an inline meter with EHEDG certification at a good price. The non-contact solution eliminated the hygiene risk.
Another case we handled in Mexico involved hot asphalt at 160 °C inside a DN100 carbon steel pipe. The high-temperature Prosonic sensors held signal strength above 28 dB for three months continuously. The plant manager now orders a spare set of sensors from Silver Instruments yearly to prevent downtime.
When to Call Silver Instruments for Your Prosonic Setup
We stock the Prosonic Flow W 400 and 93W configurations and can ship within one week to Australia, Southeast Asia, the Middle East, and Africa. Our engineers pre-load your pipe data and fluid parameters into the transmitter before dispatch. You only need to strap the sensors, apply gel, and power on. If you run into a weak signal or need help with a difficult fluid such as liquid sulfur or palm oil, just reach out. Tell us your pressure in bar, temperature in Celsius, pipe size in DN, and flow range. Email [email protected] or send a message on WhatsApp at +86 25 52155837. We also answer WeChat inquiries at +86 13512131526.
FAQ
Can Prosonic clamp-on meters measure gas? No, these ultrasonic meters work only with liquids. For gas flow, Silver Instruments supplies thermal mass and Coriolis flow meters.
What pipe materials are compatible? Standard materials such as stainless steel, carbon steel, PVC, HDPE, and copper work well. Old concrete or heavily corroded pipes may require surface grinding and a special gel. If the pipe lining is loose, the signal may scatter.
Do I need to stop the flow to install the sensors? No, that is the main advantage. You clamp the sensors onto the outside of the pipe while the line is running at full production.
How can I get a Prosonic flow meter from Silver Instruments? Send your pipe size (e.g., DN80), fluid name, temperature, and pressure to [email protected]. We will prepare a quote with the complete package including transmitter, sensors, coupling gel, and mounting hardware.
What should I do if the signal is weak on a slurry line? Check that the pipe is nearly full. For thin slurries with some solids, use a dual-path sensor if possible or move the sensor to a vertical riser section. We also offer electromagnetic flow meters for conductive slurries as a backup option.
