Frequently Asked Questions
Find clear answers to common questions about our flow meters,
applications, installation, service, and support.
What is a flow meter and how does it work?
A flow meter measures the rate or total quantity of a liquid, gas, or steam moving through a pipe. The sensing principle depends on the meter technology and the process conditions.
Which type of flow meter is right for my application?
The right choice depends on the fluid, pipe size, flow range, pressure, temperature, required accuracy, installation conditions, output requirements, and budget. Share your process data with our application engineers for a model-specific recommendation.
What information is needed to select a flow meter?
Please provide the medium, minimum and maximum flow, operating pressure and temperature, pipe material and diameter, connection type, desired output, power supply, and any hazardous-area or material requirements.
What flow meter technologies are available?
Available product families may include electromagnetic, Coriolis, vortex, turbine, thermal, ultrasonic, and positive-displacement meters. Refer to the current product pages and datasheets for model availability.
Can one flow meter measure liquids, gases, and steam?
Meter suitability is technology and model specific. Some technologies are intended mainly for conductive liquids, while others are suited to gases, steam, or a wider range of fluids. Confirm the medium and operating conditions before selection.
Which output and communication options can I request?
Output and communication choices vary by model. Include your control-system requirements in the enquiry so the quotation can confirm the available analog, pulse, alarm, or digital communication options.
How much straight pipe is required?
Required upstream and downstream straight-pipe lengths depend on the meter technology, model, and nearby disturbances. Follow the model-specific installation manual rather than applying one rule to every meter.
Does installation orientation matter?
Yes. Orientation can affect whether the measuring tube stays full, whether gas or sediment collects, and how the sensor performs. Follow the flow arrow and the orientation guidance in the applicable manual.
What should I check for wiring, power, and grounding?
Confirm the rated power supply, terminal assignments, cable type, shielding, and grounding method in the product documentation. Isolate power before wiring and follow site safety procedures.
What affects flow meter accuracy?
Accuracy can be influenced by meter sizing, flow profile, installation, fluid properties, operating range, temperature, pressure, vibration, entrained gas, coating, and calibration conditions.
Are flow meters supplied with calibration documentation?
Calibration and documentation options depend on the selected product and order. State your certificate and traceability requirements during quotation so the supplied documentation can be confirmed.
How can I verify performance after installation?
Review the installation, wiring, zero condition, process stability, and configured parameters first. For a formal performance check, follow the model guidance or contact technical support with the meter details and observed readings.
What routine maintenance is recommended?
Routine work may include inspecting wiring and grounding, checking for leakage or damage, reviewing diagnostic messages, looking for coating or blockage, and scheduling verification according to the process and site procedures.
How should a flow meter be cleaned?
Use a cleaning method compatible with the meter design, wetted materials, and process residue. Isolate and depressurize the line first, and follow the product manual and site safety requirements.
Why are the readings unstable?
Possible causes include air or solids in the line, an incompletely filled pipe, vibration, poor grounding, electrical noise, an unsuitable flow range, disturbed flow, or changing process conditions. Record the symptoms and diagnostics before contacting support.
What information should I include in a quotation request?
Include the application data, preferred meter type or model, process connection, materials, output, power supply, quantity, required documentation, delivery destination, and any special inspection or certification needs.
How is the order lead time determined?
Lead time depends on the model, configuration, quantity, documentation, production schedule, and destination. The expected schedule will be stated in the quotation or order confirmation.
Which shipping documents are supplied?
Documents vary with the order and destination. List any commercial, packing, origin, inspection, or other documentation requirements before ordering so availability can be confirmed.
What warranty terms apply to my flow meter?
Warranty terms can vary by product and order. Refer to the warranty statement in your quotation or order documentation, or contact support with the model and serial number for confirmation.
How do I request a return or service evaluation?
Contact the sales or support team before shipping equipment back. The team will confirm the applicable process, return information, and any preparation or decontamination requirements.
What product information is required for a return?
Provide the model, serial number, order reference, reason for return, process medium, service history, observed fault, and contact details. Additional safety information may be requested before equipment can be accepted.
What should I provide when contacting technical support?
Send the model and serial number, application data, installation photos, wiring details, configured parameters, diagnostic messages, current readings, expected readings, and a clear description of when the issue occurs.
Where can I find the correct manual or datasheet?
Check the relevant product page or contact the team with the exact model and version. Using model-specific documentation helps avoid applying settings or installation guidance from a different product.
Can support help troubleshoot a meter remotely?
Remote troubleshooting may be possible when sufficient installation, configuration, diagnostic, and process information is available. The support team will advise whether further checks or a service evaluation are needed.
