Description
1. Overview of the KNKE Stainless Steel Electromagnetic Flowmeter
The KNKE stainless steel electromagnetic flowmeter is designed using high-quality 304SS, 316SS, and 316L stainless steel. It features a lining made of PTFE (polytetrafluoroethylene) or full stainless steel. The flowmeter ensures high measurement precision because its induced voltage signal has a linear relationship with the average flow velocity. Unlike other flowmeter types, this device remains unaffected by changes in fluid density, viscosity, temperature, pressure, or conductivity. Here are its key features:
- No obstructing components: The flowmeter avoids adding pressure loss, making it highly efficient.
- Long-lasting sensor: Since the sensor has no moving parts, it requires less maintenance and lasts longer.
- Short straight pipe section: The induced voltage signal forms across the entire magnetic field, so the straight pipe length only needs to be 5 times the diameter of the pipe.
- Corrosion and abrasion resistance: The sensor’s electrode and lining materials are chosen to resist corrosion and wear when exposed to various liquids.
