Categories in Flow Meters - Precise Fluid Flow Measurement (11)
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. Browse our selection below or contact us to speak with a product expert.

Turbine Flow Meters

Turbine flow meters are advanced instruments designed to measure fluid flow by utilizing the rotation of a turbine within the fluid stream. These meters are widely employed in aerospace, petrochemical, and water management industries to provide accurate and real-time data on flow rates. Turbine flow meters excel in applications where precision is crucial, offering high accuracy and reliability. They play a pivotal role in optimizing processes, monitoring consumption, and ensuring the efficient operation of various systems.

Sight Flow Indicators

Sight flow indicators are essential instruments used to visually monitor the flow of liquids and gases in a pipeline or process system. These transparent or glass-tube indicators allow operators to observe the presence, color, clarity, and flow rate of fluids, ensuring smooth operations and providing valuable insights into the process. Sight flow indicators are commonly used in industries like chemical processing, petrochemicals, pharmaceuticals, and water treatment, where real-time flow observation is critical for safety, quality control, and troubleshooting. With a wide range of designs and materials available, sight flow indicators offer reliable and easy-to-use solutions for monitoring fluid flow and ensuring the efficiency of industrial processes.

Anemometer Flow Meters

Anemometer Flow Meters are specialized instruments designed to measure air or gas flow velocity. These devices are crucial in various applications, including HVAC systems and environmental monitoring. They provide accurate data on airflow rates, helping optimize ventilation, ensure safety, and enhance energy efficiency in diverse settings.

Accessories and Parts

Flow meter accessories and parts are components used to enhance the functionality, accuracy, and performance of flow meters in various industrial applications. These accessories include items such as flow totalizers, transmitters, calibration equipment, and mounting hardware, which extend the capabilities of flow meters for measuring and monitoring fluid flow rates. Browse our selection below or contact us to speak with a product expert.

Water Meters

Water Meters are essential tools for accurately measuring water consumption. These devices play a vital role in utilities, residential, and industrial settings by providing precise data on water usage. Water Meters contribute to efficient resource management, billing accuracy, and water conservation efforts, making them indispensable for monitoring and optimizing water distribution systems.

Visual Flow Meters

Visual Flow Meters offer real-time insights into fluid dynamics. With intuitive visuals, these meters provide accurate flow monitoring for optimal control in diverse applications, ensuring efficiency and precision.

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.

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 at Centro will be glad to assist.

Its inline design provides superior accuracy through direct liquid contact, particularly at low flow rates and in smaller pipe diameters. With an industry-leading 250:1 turndown ratio, it maintains consistent accuracy across widely fluctuating flow conditions. The DUK utilizes transit time difference technology with dual-function sensors and features user-friendly elements including two configurable outputs for switching, batching, and transmitting functions. The digital touch screen rotates in 90° increments for optimal viewing in any installation position, while the future-proof design allows for straightforward onsite electronics replacement."

Kobold KSK - Polyamide Material Plastic Flowmeter and Switch
MPN:KOBOLD-00-KSK-PA
The KOBOLD KSK plastic flowmeter and switch delivers reliable flow measurement for liquids and gases in a corrosion-resistant package featuring polyamide or polysulfone construction that stands up to aggressive acids and alkaline solutions typically unsuitable for metal units. Operating on the variable-area principle with a PVDF float traveling within a clear conical measuring tube, this versatile instrument provides ±4% full scale accuracy across a wide measurement range from 0.006 GPM to 4.4 GPM for liquids or from 0.06 SCFM to 62 SCFM for air (with polysulfone models offering specialized calibration scales for pressures from 0 to 145 PSIG). The compact design can be equipped with either bistable reed contacts (N/O or N/C) or NPN transistor switches featuring LED status indication, providing reliable flow monitoring and alarm capabilities for critical process protection applications. With a maximum pressure rating of 145 PSIG and temperature capabilities up to 212°F (for polysulfone versions with brass or stainless steel fittings), these shock-proof instruments offer exceptional chemical compatibility while maintaining visual indication through their clear measuring tubes. Versatile connection options including PVC glue socket/NPT female fittings or brass/stainless steel NPT adapters in various sizes make the KSK series adaptable to numerous industrial applications requiring chemical resistance combined with accurate flow measurement and control.
