IMPELLER

IMPELLER is a brand associated with flow instrumentation and fluid-handling components, with a product line centered on paddlewheel flowmeters for water and energy measurement. The brand's catalog includes both inline and insertion-style paddlewheel sensors, along with related transmitters and pumps. These devices are used to measure volumetric flow and, in some configurations, energy consumption in water-based systems. The product family is characterized by a focus on practical, application-specific specifications rather than broad, multi-purpose claims. For technical buyers, the relevant details are the measurable parameters: body materials, seal materials, connection sizes, insertion lengths, output signal types, and accuracy tolerances. IMPELLER paddlewheel flowmeters are available with polycarbonate, PPS, or stainless steel bodies, with seals in EPDM or Viton. Inline models, such as the SKU 49DF15, use NPT connections (e.g., 1 1/2 in) and provide flow measurement in gallons per minute with an accuracy of +/-2%. Insertion-style models, such as those in the 49DF24 through 49DF31 range, offer insertion lengths of 10 inches or 36 inches, with accuracy of +/-1%. Output options include standard frequency pulse and 4-20 mA, with some units featuring a digital display. Maximum voltage for these insertion sensors is 35V DC. Mounting orientation is typically horizontal. These flowmeters are intended for water flow measurement in industrial piping systems, and the energy flowmeter variant is designed for BTU measurement in hydronic applications. 3G Electric supplies the IMPELLER line as part of its industrial equipment offering. The company provides access to these flowmeters and related components, allowing procurement specialists and plant engineers to source specific SKUs, compare technical specifications, and obtain quotes. 3G Electric operates with a global reach, serving customers across different regions. The product data available through 3G Electric includes key specifications such as accuracy, flow range, connection type, body material, seal material, output type, and maximum voltage, enabling informed selection based on application requirements. For maintenance managers and plant engineers, the IMPELLER paddlewheel flowmeter line offers a range of configurations to match different pipe sizes and signal integration needs. The inline models are suited for smaller pipe diameters with NPT connections, while the insertion-style models accommodate larger pipes or retrofit installations where a 10-inch or 36-inch insertion depth is required. The choice between frequency pulse and 4-20 mA output depends on the receiving control system. The availability of stainless steel and Viton options addresses compatibility with varied water qualities and temperatures. 3G Electric's role is to make these specifications accessible and to facilitate the procurement process for these components. The brand's product range, as represented in the 3G Electric catalog, is focused on water flow measurement and energy monitoring, with a clear emphasis on paddlewheel technology. This technology is well-established for its repeatability in clean water applications and its relatively low pressure drop compared to some other flow measurement methods. The IMPELLER line does not claim to cover all flow measurement scenarios; it is specifically positioned for water and water-based energy systems. Technical buyers should review the individual SKU specifications to confirm compatibility with their system's pressure, temperature, and fluid conditions. 3G Electric provides the platform to view these details and request further information or pricing.

Frequently asked questions

Common questions about IMPELLER from 3G Electric.

What is the difference between IMPELLER inline and insertion-style paddlewheel flowmeters?

IMPELLER inline paddlewheel flowmeters, such as SKU 49DF15, are installed directly in the pipe run and use NPT connections (e.g., 1 1/2 in). They are typically used for smaller pipe sizes. Insertion-style models, such as SKUs 49DF24 through 49DF31, are mounted through a fitting and have a probe that extends into the flow stream. They are available with 10-inch or 36-inch insertion lengths, making them suitable for larger pipes or retrofit installations. Insertion models generally offer +/-1% accuracy, while the inline model listed has +/-2% accuracy. Output options also differ: inline models may provide a direct reading, while insertion models offer frequency pulse or 4-20 mA outputs.

What materials are used in IMPELLER paddlewheel flowmeters?

IMPELLER paddlewheel flowmeters are available with different body and seal materials depending on the model. The inline SKU 49DF15 has a polycarbonate body and EPDM seal. Insertion-style models come with either a PPS body (e.g., SKU 49DF24) or a stainless steel body (e.g., SKUs 49DF25 through 49DF31). Seal materials for insertion models include EPDM and Viton. The choice of material affects compatibility with the fluid and operating conditions. Stainless steel and Viton are often selected for more demanding water applications, while polycarbonate and EPDM are used in standard water systems. Buyers should verify chemical compatibility and temperature limits for their specific process.

What output signals do IMPELLER insertion-style flowmeters provide?

IMPELLER insertion-style paddlewheel flowmeters offer two main output types: standard frequency pulse and 4-20 mA. For example, SKU 49DF24 provides a standard frequency pulse output, while SKU 49DF28 provides a 4-20 mA output. Some models, such as SKU 49DF31, include a digital display in addition to the 4-20 mA output. The maximum voltage for these sensors is 35V DC. The choice between pulse and analog output depends on the input requirements of the receiving control system, data logger, or PLC. Frequency pulse is often used for totalizing, while 4-20 mA is used for continuous monitoring and control.

What is the accuracy of IMPELLER paddlewheel flowmeters?

Accuracy varies by model. The inline IMPELLER paddlewheel energy flowmeter (SKU 49DF15) has an accuracy of +/-2%. The insertion-style paddlewheel flowmeters (SKUs 49DF24 through 49DF31) have an accuracy of +/-1%. These figures are typically specified under reference conditions and may be affected by installation, fluid properties, and flow profile. For critical applications, consider the entire measurement chain, including the flowmeter, transmitter, and installation. The stated accuracy is a key specification for assessing whether the device meets the requirements of a given process.

Can IMPELLER flowmeters be used for energy measurement?

Yes, the IMPELLER inline paddlewheel energy flowmeter (SKU 49DF15) is designed for BTU measurement in water systems. It measures water flow and, when paired with temperature sensors, can calculate energy consumption. This type of meter is commonly used in hydronic heating and cooling systems to allocate energy costs or monitor system performance. The insertion-style models listed are primarily for water flow measurement and do not include energy calculation as a standard feature. For energy monitoring, the inline energy flowmeter is the specific model to consider.

What are the mounting requirements for IMPELLER paddlewheel flowmeters?

IMPELLER paddlewheel flowmeters are typically designed for horizontal mounting. This orientation helps ensure proper bearing lubrication and accurate flow measurement. The inline model (SKU 49DF15) is specified for horizontal mounting. Insertion-style models also indicate horizontal mounting orientation in their specifications. Installation should follow the manufacturer's guidelines regarding straight pipe runs upstream and downstream to minimize turbulence and maintain accuracy. The insertion length (10 in or 36 in) must be appropriate for the pipe size and fitting used. Proper installation is essential for achieving the stated accuracy and reliable operation.
