Quick Answer: Silver Automation Instruments supplies ultrasonic flow meters that track fluid velocity with acoustic wave sensors on pipes from DN15 to DN3000. These meters handle clean water, wastewater, chemicals, and light hydrocarbons with no moving parts. Send your pipe size, fluid type, temperature, and pressure for a quotation.
Ultrasonic meters send acoustic waves through the pipe wall or directly through the fluid. The meter measures transit time difference between upstream and downstream signals. That value gives volumetric flow rate directly. There is no moving part in the flow stream. Most engineers choose this technology when they need a non-invasive clamp-on installation or a low maintenance inline meter.
In practice, a clamp-on meter saves downtime. You do not cut the pipe or stop production. A technician mounts transducers on the outside of a DN50 or DN300 line and checks signal strength. The electronics convert the time difference into flow rate in cubic meters per hour or liters per minute.
Silver Instruments offers two main types. Clamp-on ultrasonic flow meters fit existing installations. Inline ultrasonic flow meters suit new skids, water transfer lines, and building management systems. Both types output a signal that you can send to a PLC or a flow computer.
Here is the thing. Clamp-on meters have slightly lower accuracy on dirty or low density fluids. Inline meters give better performance on liquid with small particles. We often supply clamp-on models for water and wastewater audits because installation takes less than one hour on a clean pipe section. For chemical dosing or fuel oil, we recommend inline models with wetted materials such as 316L stainless steel or PTFE.
A water utility in Indonesia used a clamp-on ultrasonic flow meter to verify a DN600 raw water line without shutting down the supply. A brewery in Vietnam installed an inline model on a DN80 CIP return line. The meter sends 4-20 mA HART data to the brewery control room. A desalination plant in Oman selected a seawater flow meter for feed lines with high salt content. A paint manufacturer in the Philippines measured solvent flow with a PTFE lined inline meter.
These examples share one thing. The end users wanted a meter that does not drift after a few months. They also wanted local technical support and fast spare availability. Silver Instruments ships to Australia, Chile, Nigeria, and Saudi Arabia from stock and provides remote startup support over WhatsApp or WeChat.
Standard ultrasonic flow meters from Silver Instruments offer accuracy of ±0.5 percent to ±1.0 percent of reading depending on pipe conditions and fluid type. Flow velocity range is 0.01 m/s to 25 m/s. Process temperature ratings cover -20 °C to 160 °C for clamp-on transducers. Inline models can be ordered for higher temperatures with remote electronics.
Outputs include 4-20 mA HART, pulse, and RS485 Modbus RTU. The electronics can be powered by 24 VDC or 85 to 265 VAC. Enclosure rating is IP67 for field mounting. For hazardous areas, ask about ATEX Zone 1 or Zone 2 versions. A PT100 input is available for temperature compensation. The display can show m3/h, L/min, or kg/h. We size the meter using your pipe material, wall thickness, fluid type, and pipe diameter. Carbon steel, stainless steel, and PVC pipes all work with clamp-on models if the pipe wall is not excessively corroded.
Do not send a vague inquiry. We can respond faster if you include these details: pipe outer diameter, pipe wall thickness, pipe material, fluid name, process temperature, pressure, and required output signal. A typical RFQ line looks like this: DN150 carbon steel pipe, city water, 25 °C, 4 bar, 4-20 mA HART output.

Can a clamp-on ultrasonic flow meter measure wastewater with small solids? Yes, but signal strength drops when the liquid has a high concentration of gas bubbles or suspended solids above roughly 10,000 ppm. We recommend a Doppler type or an inline magnetic flow meter in that case.
What is the minimum straight pipe length for ultrasonic flow meters? We use 10D upstream and 5D downstream for most clean liquid applications. For pumps or partially open valves, use 20D upstream to get stable readings.
Do I need to stop the process for clamp-on installation? No. The transducers mount on the outside of a live pipe. You do not need to cut, weld, or drain the line.
Can these meters measure diesel or light oil? Yes. Inline ultrasonic meters work on clean diesel, light fuel oil, and some solvents. Clamp-on models work best on dense liquids with good acoustic coupling. For viscous oils above about 50 cP, ask our engineers to check the application.
Which data output works best for SCADA systems? Most customers pick 4-20 mA HART for analog input cards or RS485 Modbus RTU for digital polling. Both are available on standard models.
