Materials of Construction
Housing: AluminumWetted parts: 316 Stainless Steel Static seals: Buna or Viton |
Design Features
The LC Pulse Output Device (POD) converts the rotary motion created during the process of fluid measurement through an LC Meter into a high resolution, unscaled pulse stream. This pulse stream is provided by a magnetically coupled optical encoder that has a signal which is directly proportional to the liquid flow through the meter.
Glandless Drive...
No dynamic seals to fail and leak. All wetted parts are 316 Stainless Steel or equivalent. Meets Weights and Measures requirements. Weatherproof UL/CSA Type 4X and IP66 design. High Resolution, Square Wave, Single or Dual Channel Pulse Output.
