As a premier magnetic level gauge manufacturer based in Baton Rouge, Louisiana, Jogler, LLC provides safe, economical, and reliable solutions for measuring and controlling liquid levels across a wide range of process pressures, temperatures, and fluids. Jogler offers two core products: Magnetic Level Gauges and Armored Liquid Flow Indicators.
Our high-quality magnetic level gauges are engineered for precision and durability, serving critical applications throughout the USA and globally. Each component is designed to ensure dependable, maintenance-free operation, meeting the stringent demands of modern industrial environments.
Key Features and Engineering Excellence
- Extruded Outlets: We utilize extruded outlets on our chambers to ensure smooth, reliable float travel. This advanced manufacturing process allows for full-bore connections, eliminating chamber distortion and internal protrusions that can impede float movement. Jogler offers superior extruded outlet level gauges.
- Deep-Drawn Floats: To reduce the potential for stress cracking and failure, our floats are constructed from deep-drawn halves, minimizing welds. This seamless design enhances the durability and longevity of our magnetic gauges.
- Optimized Magnetic Coupling: Our design features an optimized magnetic circuit that ensures a strong, reliable coupling between the internal float and the external indicator, even through thick chamber walls.
- Durable Indicator Construction: Jogler’s unique two-piece flag rail design prevents temperature-related distortion and breakage, ensuring clear and consistent level indication.
Armored flow style liquid flow indicators and Direct-Reading Armored Flow Indicators from Jogler deliver clear, leak-proof visibility of liquid flow in process vessels. These products are built for reliability and ease of use, ideal for industrial applications requiring precision and long-lasting performance. Below are a key set of features for our Jogler armored flow indicators.
- Direct-Reading Armored Flow Indicator: Maximal sight tube protection with high visibility
- Material Options: Powder-Coated Carbon Steel, 316/316L Stainless Steel, and PTFE Teflon-lined connectors
- Chemical Compatibility: Suitable for a wide range of fluids; Optional FEP Teflon liner
- Sealing Technology: Five independent tube-sealing ridges (seven for tube-in-tube models) using patented PTFE Teflon SuperSeals for leak-free, stress-free installation
- FM Approval: Designed and approved for safe use with flammable liquids
- Large Diameter Options: Up to 8” flange sizes
- Long Gauge Lengths: Up to 4ft per section, reducing joints and leak points
