IMPELLER

IMPELLER is a brand specializing in paddlewheel flow measurement technology, offering a range of electronic flowmeters and transmitters designed for water and fluid monitoring applications. The product line includes insertion-style and inline paddlewheel flow sensors, as well as BTU system meters and signal transmitters, all engineered for industrial and commercial use. IMPELLER flowmeters are constructed with materials such as stainless steel, bronze, polycarbonate, and polyphenylene sulfide (PPS), with seal options including Viton and EPDM to accommodate various fluid compatibility requirements. These devices are available in multiple insertion lengths (e.g., 10-inch and 36-inch) and pipe sizes (e.g., 1-inch to 2.5-inch NPT), with accuracy ratings of ±1% or ±2% depending on the model. Output types include standard frequency pulse, scaled pulse, and 4-20 mA analog signals, with maximum voltage ratings up to 35V DC or 28V AC. Some models feature digital displays for local readout, while others are designed for remote output integration. The transmitters, such as the polypropylene model (MPN 8320-00), provide scaled pulse outputs and operate within a temperature range up to 158°F. IMPELLER products are typically used for water flow measurement in applications like HVAC systems, process control, and water treatment, where reliable paddlewheel technology is required. 3G Electric supplies these IMPELLER flowmeters and transmitters globally, supporting plant engineers and maintenance managers with a selection of models that meet standard industrial specifications. The brand focuses on functional, field-proven designs without unnecessary complexity, making them suitable for straightforward flow monitoring tasks. All units are calibrated for gallons measurement, and the insertion-style sensors allow for installation in larger pipes without system shutdown. The inline tee-type sensors provide a compact, direct-fit solution for smaller pipe diameters. IMPELLER's product range emphasizes durability and repeatability, with materials chosen for resistance to corrosion and wear in water-based environments. For procurement specialists, these flowmeters offer a balance of performance and cost-effectiveness, with specifications that align with common industrial requirements for accuracy, output compatibility, and environmental tolerance.

Common Applications

  • Water treatment plants — Insertion paddlewheel flowmeters (e.g., 8SDI1D1N00-0200) for monitoring flow in large-diameter pipes.
  • HVAC systems — Inline paddlewheel flowmeters (e.g., 8250BR1505-1211) for chilled water or condenser water loop measurement.
  • Process cooling — BTU system meters (e.g., 8380212000-1202) for energy flow measurement in cooling circuits.
  • Industrial water supply — Insertion flowmeters with 4-20 mA output (e.g., 8SDI0D2N11-0200) for remote monitoring of water usage.
  • Chemical dosing — Inline PPS flowmeters (e.g., 8228BR2505-1211) for corrosive water or chemical solutions with EPDM seals.
  • Building automation — Transmitters (e.g., 8320-00) converting paddlewheel pulse signals to scaled outputs for BMS integration.

Frequently asked questions

Common questions about IMPELLER from 3G Electric.

What types of flowmeters does IMPELLER offer?

IMPELLER offers insertion-style and inline paddlewheel flowmeters for water measurement. Insertion models (e.g., 8SDI1D1N00-0200) feature stainless steel construction with lengths up to 36 inches, while inline tee-type models (e.g., 8250BR1505-1211) are available in bronze or PPS with NPT connections from 1 to 2.5 inches. Both types provide standard frequency pulse or 4-20 mA outputs.

What is the accuracy of IMPELLER paddlewheel flowmeters?

Most IMPELLER paddlewheel flowmeters have an accuracy of ±1% of reading, as seen in models like the 8SDI1D1N00-0200 and 8250BR1505-1211. Some models, such as the BTU system meter (MPN 8380212000-1202), have an accuracy of ±2%. These ratings are typical for paddlewheel technology in water flow applications.

What materials are used in IMPELLER flowmeters?

IMPELLER flowmeters use materials including stainless steel, bronze, polycarbonate, and PPS for wetted parts. Seal materials are either Viton or EPDM, depending on the model. For example, insertion models like 8SDI1D1N00-0200 use Viton seals, while inline models like 8250BR1505-1211 use EPDM. Material selection depends on fluid compatibility and application requirements.

What output signals do IMPELLER flowmeters provide?

IMPELLER flowmeters offer standard frequency pulse outputs (e.g., 35V DC max) on models like 8SDI1D1N00-0200, and 4-20 mA analog outputs on models like 8SDI0D2N11-0200. Transmitters like the 8320-00 provide scaled pulse outputs. These signals are compatible with PLCs, controllers, and remote monitoring systems.

Can IMPELLER flowmeters be used for hot water applications?

Yes, IMPELLER flowmeters are designed for water applications, including hot water. The transmitter model 8320-00 has a maximum operating temperature of 158°F. Flow sensors with EPDM seals are suitable for higher-temperature water, while Viton seals offer broader chemical resistance. Always verify the specific model's temperature rating for your application.

What is the difference between insertion and inline IMPELLER flowmeters?

Insertion IMPELLER flowmeters (e.g., 8SDI1D1N00-0200) are installed through a pipe wall, suitable for larger pipes (e.g., 10-inch or 36-inch insertion length) without cutting the line. Inline tee-type models (e.g., 8250BR1505-1211) are installed directly in the pipe run, available in sizes from 1 to 2.5 inches NPT. Both use paddlewheel technology but differ in installation method and pipe size compatibility.
