Siemens Clamp On Flow Meter: Sitrans Non-Invasive Pipe Transducers for Tough Industrial Jobs
Quick Answer: Siemens Sitrans clamp-on flow meters measure liquid flow from outside the pipe. No cutting, no welding, no process shutdown. These non-invasive ultrasonic transducers handle pipes from DN15 to over DN3000, pressures up to 400 bar, and temperatures from -40 °C to 200 °C. Silver Automation Instruments supplies the full Sitrans FUS range with factory pricing and fast delivery to Southeast Asia, Oceania, Africa, and the Middle East.
What Makes Non-Invasive Clamp-On Flow Measurement Practical
Plenty of plants still use inline flow meters that require pipe modifications. That costs time and money. A clamp-on ultrasonic flow meter eliminates those steps. You simply strap the transducers onto the outside of an existing pipe. The meter works immediately. This is useful when you deal with corrosive chemicals, high-purity water, or pipes you cannot shut down.
Siemens Sitrans FUS sensors use the transit time ultrasonic principle. They send ultrasonic pulses through the pipe wall and the liquid. One pulse travels with the flow, another against it. The meter calculates the difference in transit time. That difference is proportional to flow velocity. Multiply by the known pipe cross-section and you get volumetric flow rate. It is straightforward physics and it works well on clean liquids with minimal solids or gas bubbles.
Key Models We Stock and Configure
Silver Instruments keeps several Sitrans clamp-on variants in our project pipeline. We do not carry everything in shelf stock but we configure orders within 3 working days. Three main series cover most customer requests.
Sitrans FUS060 is the entry-level transmitter with a basic local display. It outputs 4-20 mA and a pulse signal. It fits simple water and clean chemical applications where you do not need HART or Modbus. Pipe diameter range is DN15 to DN2000. Temperature limit is 100 °C for standard transducers. It ships with DS-300 mounting fixtures and coupling gel.
Sitrans FUS380 adds HART 7 and Modbus RTU communication. It handles bidirectional flow measurement and stores up to 100 data points in the logging memory. The transmitter housing is IP67 aluminum. We see a lot of demand for this model from chilled water systems in the Philippines and chemical batching in Indonesia. Pipe sizes go up to DN3000. Accuracy is 0.5 % of reading under stable conditions.
Sitrans FUS1010 uses the dual-beam WideBeam transducer technology. It measures liquids with a higher percentage of suspended solids or gas bubbles where standard Doppler or single-beam clamp-on meters fail. This model appears often in mining slurry lines and wastewater lift stations. It works on metal and plastic pipes, including lined pipes. You can measure flow on PE, PVC, steel, and ductile iron without cutting. It also handles high-temperature thermal oil circuits up to 200 °C when you use the high-temperature coupling pads.
Installation Reality: What Engineers On Site Actually Face
Most engineers skip this part. But we have seen many customer sites in Vietnam, Nigeria, and Chile, so here it goes. The pipe surface matters. You must remove paint, rust, and loose scale. A smooth contact zone ensures the ultrasonic signal couples properly. On old carbon steel pipes with heavy pitting, even the best meter will struggle. We always ask for a pipe condition report before recommending a clamp-on solution.
Straight pipe run requirements are identical to any velocity flow meter. You need at least 10 pipe diameters upstream and 5 downstream from valves, elbows, or pumps. A half-empty pipe or a vertical downflow with partial fill will give wrong readings. The liquid must be fully filling the pipe cross-section.
Coupling gel or pads are mandatory. For permanent installations above 80 °C, use the solid coupling pads, not the gel. The gel dries out over time. We include a tube of coupling compound in every shipment. The mounting rails and straps work well for pipe sizes up to DN300. For larger pipes, you need chains or custom brackets, which we can source from Siemens.
Where Clamp-On Meters Beat Inline Meters In Real Projects
We regularly quote clamp-on meters for desalination plants, district cooling loops, and food-grade CIP systems. Here are a few concrete examples from recent inquiries.
A palm oil refinery in Malaysia needed to measure edible oil flow on an existing DN100 stainless pipe. Production cou
A water utility in Peru asked for a portable flow survey tool. They needed to verify permanent meter accuracy across several remote pumping stations. We proposed the portable Sitrans FUP1010 with rechargeable battery. The operator moves from station to station, clamps the transducers on, takes readings, and leaves. No shutdowns. They recently ordered two additional kits for other regions.
A desalination plant in Oman uses clamp-on meters on the brine reject line. The DN800 GRP pipe carries highly concentrated saltwater at 40 °C. Inline magmeters would require exotic materials and large flanges. The clamp-on solution saved about 60 % on total installed cost compared to an inline meter with titanium electrodes.
Technical Specs Engineers Usually Ask For

Sitrans Clamp-On vs Other Technologies In Our Portfolio
Silver Instruments manufactures or distributes Coriolis mass flow meters, electromagnetic flow meters, oval gear flow meters, vortex flow meters, and thermal mass flow meters. The clamp-on ultrasonic meter fills a specific niche. It works when you cannot break the pipe, when you need a temporary measurement point, or when you measure large diameters where inline meters become too expensive.
But it is not a universal tool. If your liquid contains more than 3 % solids or a lot of entrained gas, a Coriolis meter or a full-bore magmeter with a grounding ring may be more reliable. In our application support, we often cross-check the process data before confirming a clamp-on quote. This saves the customer hassle later. We have done this for a paint factory in Thailand and a beer brewery in Mexico. The customer appreciates an honest recommendation.
Pricing and Lead Time Specifics
A basic Sitrans FUS060 kit for a DN50 carbon steel pipe starts around USD 1,800 ex-works. The price increases with larger transducers, high-temperature pads, and additional communication options. A fully specified Sitrans FUS1010 for a DN400 pipe with Modbus and remote mounting brackets sits in the USD 4,500 to USD 5,800 range. Shipping from our Nanjing warehouse to Indonesia or Brazil typically takes 5 to 7 days by air freight. Ocean freight is cheaper but slower. We handle all export documentation.
FAQ
Can I use a Siemens clamp-on meter on a vertical pipe with flow going down?
Only if the pipe is completely full at the measurement point. A vertical downflow often becomes partially full. Install the transducers on a horizontal run or a rising vertical line instead.
What is the minimum conductivity required for the liquid?
None. Ultrasonic clamp-on meters work on ultrasonic signal propagation, not electromagnetic induction. They measure non-conductive liquids like deionized water, oils, and solvents without any problem.
Do you offer on-site commissioning in the Middle East or Africa?
We do remote video support at no charge. For on-site commissioning, we work with local partner engineers. Contact us with your location and we check availability.
Can the meter store flow data for later download?
The Sitrans FUS380 and FUS1010 models include a data logger. You can export data via USB or Modbus. The logging interval is configurable from 1 second to 1 hour.
Which model works best for a temporary flow survey on an existing DN200 PVC pipe carrying water at 25 °C?
The Sitrans FUS060 is enough for clean water. We can also supply a portable carry case version. Include your pipe outer diameter and wall thickness in the request email.
