Flow Switches
Flow switches are vital instruments in fluid systems that detect the presence or absence of flow. These devices ensure proper operation and prevent issues such as pump damage or system failure. Flow switches are employed in various industries to monitor and control the flow of liquids or gases, providing a reliable means of safeguarding equipment and optimizing fluid processes.
Flow Sensors
Flow Sensors are key elements in fluid systems, detecting and measuring the flow rate. These devices offer real-time data on liquid or gas movement, enabling precise control and monitoring. Flow Sensors are essential in manufacturing, healthcare, and environmental monitoring industries, providing valuable insights for process optimization, quality control, and regulatory compliance.
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 at Centro. They'll be glad to assist you.

At Centro, we carry a complete online selection of flow meters, including magnetic flow meters, turbine flow meters, and positive displacement flow meters. We also offer a variety of accessories and replacement parts to ensure that your flow meter always operates at peak efficiency. Whether you're looking for a new flow meter or need to restock your supplies, Centro has everything you need to keep your operation running smoothly.
Flow Transmitters
Flow Transmitters are essential in fluid systems, accurately measuring and transmitting flow rate data. These devices play a critical role in monitoring and controlling the flow of liquids or gases in various applications. By providing real-time information, Flow Transmitters enable precise adjustments, ensuring optimal performance and efficiency. Their reliability and accuracy make them indispensable for industries where precise flow measurement is crucial.
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.

The robust construction featuring brass or 316L stainless steel housing options combined with a sapphire axle/bearing assembly ensures outstanding durability and extended service life even in demanding industrial environments. Multiple output options—from basic frequency pulse signals to sophisticated 4-20 mA outputs and programmable compact electronics with integrated digital display—provide flexible integration with various control systems while maintaining measurement consistency across flow ranges from 0.24 GPH to 80 GPH. The sensor's versatile design allows mounting in any orientation with the axle maintained in the horizontal plane, facilitating straightforward installation in challenging locations while delivering reliable performance with an operating temperature range of -10°F to 176°F and pressure ratings up to 230 PSIG.
