How to Choose the Correct Flow Meter
Choosing the correct flow meter requires accurate application information.
1. Identify the Fluid
Tell us exactly what is being measured:
- Water
- Sewage
- Slurry
- Diesel
- Oil
- Chemical
- Gas
- Steam
- Compressed air
- Food product
- Other process fluid
The fluid’s conductivity, viscosity, density, solids content and chemical properties can significantly affect meter selection.
2. Confirm Pipe Size
Provide the pipeline size, for example:
DN25, DN50, DN80, DN100, DN150, DN200, DN300, DN500, DN800 or DN1000.
For an existing installation, provide the actual pipe size and connection standard where possible.
3. Provide Minimum, Normal and Maximum Flow
Do not provide only the normal flow rate.
Ideally provide:
Minimum flow: ___ m³/h
Normal flow: ___ m³/h
Maximum flow: ___ m³/h
This helps determine the appropriate meter range and turndown.
4. Confirm Pressure and Temperature
Provide:
- Minimum pressure
- Normal pressure
- Maximum pressure
- Minimum temperature
- Normal temperature
- Maximum temperature
This is especially important for steam, chemicals, oil and high-temperature applications.
5. Specify Required Output
The flow meter may need:
- Local display
- 4–20 mA
- Pulse output
- Frequency output
- HART
- Modbus RTU
- Profibus
- PROFINET
- Ethernet/IP
- RS485
- Relay outputs
- Totaliser
- Digital communication to PLC/SCADA
Flow Meter Installation Tips
Tip 1 – Check the Pipeline
Confirm:
- Pipe diameter
- Pipe material
- Flange standard
- Pressure rating
- Connection type
- Available installation space
Tip 2 – Check Straight Pipe Requirements
Some flow technologies require adequate upstream and downstream straight pipe.
Always follow the manufacturer’s installation requirements.
Tip 3 – Avoid Incorrect Sizing
A flow meter should not simply be selected because it matches the pipe diameter.
The minimum and maximum operating flow must also be considered.
Tip 4 – Consider the Fluid
An electromagnetic flow meter is generally suitable for conductive liquids, while other technologies may be better for gases, steam, hydrocarbons or non-conductive liquids.
Tip 5 – Consider the Environment
For outdoor, underground, wet or washdown applications, check:
- IP rating
- Temperature
- UV exposure
- Flooding risk
- Chemical exposure
- Vibration
Tip 6 – Check Calibration
For critical measurement applications, consider calibration and verification requirements.
Tip 7 – Specify the Communication Protocol
If the meter connects to a PLC or SCADA system, specify the required communication interface before ordering.
Tip 8 – Consider Total Cost of Ownership
Do not select a flow meter based only on the purchase price.
Consider:
- Installation
- Calibration
- Maintenance
- Replacement parts
- Electronics
- Communication
- Downtime
- Expected service life
