Endress Hauser Ultrasonic Flow Meter Manual PDF: Prosonic Flow Installation and Settings
Quick Answer: This page covers the main installation and settings steps for Endress Hauser Prosonic Flow ultrasonic flow meters. If you need a replacement meter, spare sensors, or a low cost clamp-on alternative, send Silver Automation Instruments your pipe size in DN, fluid type, temperature in °C, and flow range. We will reply with a quote and manual.
Silver Instruments is not affiliated with Endress Hauser. Prosonic Flow is a trademark of its owner. We write this guide because many engineers search for the Endress Hauser Ultrasonic Flow Meter Manual PDF and then ask us for installation support or a second source.
Prosonic Flow Installation and Settings: What Engineers Actually Need
Most Prosonic Flow meters use transit-time technology. The sensor pair sends ultrasonic signals through the pipe wall and liquid. Installation is not hard if you follow the pipe preparation and sensor spacing rules. Here is the thing. Most commissioning issues on customer sites come from bad pipe surface prep, wrong wall thickness input, or poor sensor alignment.
In practice, we have seen this on customer sites in Vietnam, the Philippines, and Saudi Arabia. A water treatment plant in Manila had unstable readings because the pipe was coated with rust and the sensor spacing was off by 3 mm. After cleaning the surface and re-entering the actual wall thickness, the signal strength went back to normal.
Sensor Mounting and Pipe Preparation
Clean the pipe surface down to bare metal. Remove rust, paint, and scale over a width at least double the sensor face. Apply coupling gel or pads exactly as shown in the manual. Measure the pipe circumference and wall thickness with a caliper or ultrasonic thickness gauge. Do not rely on the nominal pipe schedule alone.
Choose a straight pipe section with 10D upstream and 5D downstream for a standard clamp-on installation. Avoid top mounting on horizontal pipes when the liquid may have bubbles or sludge. Better positions are the 3 o clock or 9 o clock sides of the pipe. For vertical pipes, flow should go upward.
For the Prosonic Flow Installation and Settings sequence, the manual normally asks for sensor type, mounting method, pipe material, pipe outer diameter, wall thickness, liner material, fluid type, and transducer frequency. Enter each value in this order. Most engineers skip the liner setting. That mistake often causes a 2 percent to 5 percent offset in flow reading.
Settings to Check Before First Startup
Set the flow unit first. Most plants use m3/h, liters per second, or kg/h for mass flow when density is fixed. Then set the output range. A common setup is 4-20 mA HART with a span of 0 to 150 m3/h for a DN200 water line. For custody transfer or energy monitoring, use pulse output or Modbus RS485.
Check the low flow cut off. A value of 0.02 m/s to 0.05 m/s is typical for clean water. High enough to zero out pump vibration or valve leakage, low enou
After the signal check, run a zero calibration with full pipe and zero flow. Write down the signal strength, sound speed, and gain values. These numbers help you diagnose future drift without opening the Endress Hauser Ultrasonic Flow Meter Manual PDF again. We keep these values in our service notes for every Silver Instruments installation.
Silver Instruments Ultrasonic Flow Meter Options
You do not need to replace your entire metering loop to test our equipment. Silver Instruments supplies clamp-on and inline ultrasonic flow meters for DN15 to DN6000 pipes. Our clamp-on series called SUF-300 handles clean water, wastewater, cooling water, seawater, and some chemical liquids with temperature up to 200 °C.
The SUF-300 supports 4-20 mA HART, pulse, and Modbus RS485. Sensor mounting follows the same transit-time rules used in most Prosonic Flow manuals. We ship an English manual with pipe data tables, wiring diagrams, and a quick start guide. Many clients in Southeast Asia, the Middle East, and Latin America use the SUF-300 for desalination plants, district cooling, textile wastewater, and food processing.
Because every installation is different, we ask for real site data before pricing. Send us your pressure in bar, temperature in °C, pipe size in DN, and flow range. Tel: +86-135-1213-1526.

FAQ: Prosonic Flow Installation and Settings
Can I use the Endress Hauser Ultrasonic Flow Meter Manual PDF for a Silver Instruments meter?
You can use it as a general reference for sensor spacing and pipe preparation. Silver Instruments ships its own manual with SUF-300 specific tables. Follow the Silver manual for final settings and wiring.
What straight pipe run is needed for a Prosonic Flow ultrasonic meter?
Use 10D upstream and 5D downstream for standard accuracy. Some installations work with less if the flow profile is stable. Check the manual for the reduced straight run correction factors.
What settings cause the most startup errors?
Wrong wall thickness, missing liner material, wrong sensor spacing, and low signal strength cause most startup errors. Enter all pipe data in the order shown in the manual. Then verify signal strength before leaving the site.
Can Silver Instruments help with an Endress Hauser Prosonic Flow replacement?
Yes. We offer clamp-on and inline ultrasonic flow meters for clean liquids, seawater, and light wastewater. Send a photo of the pipe, current meter nameplate, and your flow range in m3/h.
What is the price of a Silver Instruments ultrasonic flow meter?
Price depends on pipe size, fluid type, sensor type, and output options. Send us your pipe size in DN, temperature in °C, pressure in bar, and flow range. We usually reply within 24 hours.
