Pertanyaan umum tentang IMPELLER dari 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.
