Turbine Flow Meters
Turbine flow meters measure liquid flow by counting the rotation of a turbine rotor. They're accurate and responsive in clean, low-viscosity liquids such as water, fuels and light chemicals.
Turbine Meter Features
- High accuracy – suitable for batching and blending
- Wide turndown – broad flow range
- Pulse and analog outputs – connect to totalizers and controls
- Sanitary and stainless versions – food and chemical service
Installation Tips
Provide enough straight pipe upstream and downstream, and install a strainer to protect the rotor. Viscosity changes affect accuracy, so turbines suit consistent, clean fluids.
Centro supplies turbine flow meters for water, fuel and chemical measurement.

Ultrasonic Flow Meters
Ultrasonic flow meters use cutting-edge technology to precisely gauge the velocity of gas coursing through pipes. These meters employ transducers strategically positioned on opposite sides of the pipe. One transducer emits ultrasonic waves across the pipe, while its counterpart catches these waves. By timing the waves' journey upstream and downstream, these meters can accurately determine gas velocity. This data, when combined with the pipe's cross-sectional area, facilitates the calculation of gas flow rate. Renowned for their non-intrusive nature and versatility, ultrasonic flow meters find applications in various fields, including natural gas distribution, compressed air systems, and HVAC installations. Their appeal lies in their remarkable accuracy, wide turndown ratios, and low maintenance requirements, making them a preferred choice for gas flow measurement across industries. For further assistance and expert advice on selecting the right ultrasonic flow meter for your application, contact the product experts. They'll be glad to assist you.

Magnetic Flow Meters
Magnetic flow meters are tools for measuring the flow of liquids in various industries. They work by using a magnetic field to determine the velocity of the fluid flowing through a pipe. One of the best things about these meters is their accuracy and reliability, especially when dealing with dirty or corrosive liquids. They're commonly used in water treatment plants, chemical processing, and even in food and beverage production because they have no moving parts and don't obstruct the flow, which means less maintenance and a longer lifespan. Have your pipe size, liquid and flow range handy, and our instrumentation team can help you size a mag meter and choose the right liner and electrode materials.

Gas Flow Meters
Gas flow meters are devices used for measuring the flow rate of gases. They utilize different principles for measurement, including differential pressure, velocity, positive displacement, thermal sensing, and Coriolis effects. Differential pressure meters gauge the pressure decrease across a constriction, velocity meters gauge gas speed, positive displacement meters measure the flow rate by trapping and then releasing discrete volumes of gas, thermal meters detect heat transfer, and Coriolis meters measure the twisting of vibrating tubes. Each type has its advantages and limitations, with selection dependent on factors such as gas type, flow rate range, pressure, temperature, and required accuracy, for specific application needs. For further assistance and expert advice on selecting the right gas flow meter, the product experts will be glad to assist.

Roto Meters
Rotameters, also called variable area flow meters, show flow with a float that rises in a tapered tube. They're simple, inexpensive and need no power, so they're widely used for purge flows, gas blending, water treatment and lab systems.
Rotameter Options
- Glass tube rotameters – clear visual indication
- Plastic and acrylic meters – water and low-pressure service
- Metal tube rotameters – high pressure, temperature and opaque fluids
- Integral needle valves – set and control flow
- Transmitters and alarms – add remote signals
Choosing a Rotameter
Rotameters are calibrated for specific fluids, pressures and temperatures, so provide your conditions for accurate scaling. Install vertically with flow upward. Metal tubes suit hazardous or high-pressure lines.
