MAIN FEATURES:
A cost-effective magnetic level indicator designed for continuous level measurement in basic liquid applications. It provides reliable, local indication without the need for external power, making it ideal for water storage tanks, condensate receivers, and wash or surge tanks handling fuels, lubricants, additives, and similar chemicals. Constructed with durable materials, it offers dependable performance with minimal maintenance requirements. Its simple, float-operated magnetic coupling principle ensures accurate readings even in turbulent or dirty service conditions. Suitable for both atmospheric and pressurized vessels, this versatile gauge combines economy with robust functionality for demanding industrial environments.
