Model JMG
Magnetic Level Gauge
Jogler’s level style liquid level indicator delivers a straightforward, leak-proof method for monitoring liquid levels in tanks and vessels without compromising the integrity of your process system. Designed for industrial applications where reliability and visibility matter, these direct-reading instruments are engineered to exact customer specifications for maintenance-free service across all process industries.
Simple, Reliable Liquid Level Observation
The core function of a direct-reading liquid level gauge is to provide an accurate, real-time view of what is happening inside your vessel. Jogler’s level style indicators achieve this without complex instrumentation or frequent maintenance interventions.
Because the liquid in the transparent sight tube mirrors the level inside the tank at all times, operators receive an immediate, accurate reading at a glance. No power, no signal conditioning, no guesswork.
Patented SuperSeal Technology for Permanent, Stress-Free Sealing
All Jogler Level Style indicators incorporate patented PTFE Teflon SuperSeal inserts: the foundation of their leak-free performance.
These inserts seal on the outside diameter of the sight tube, not the ends. This design allows the tube to move freely with thermal expansion and contraction without creating stress points or gaps. The result is a permanent, bubble-tight seal that eliminates:
- Differential expansion stress between the sight tube and housing
- Gaskets and O-rings that require routine inspection and replacement
- Common leak paths associated with traditional sight glass assemblies
SuperSeal inserts last the life of the sight tubing, making the overall assembly genuinely maintenance-free once installed.
High Visibility Compared to Traditional Sight Glasses
One of the most practical advantages of Jogler’s level style liquid level indicator is enhanced visibility. Wider, clearer sight tube assemblies give operators a direct, unobstructed view that traditional sight glasses cannot match.
Standard shields are powder-coated carbon steel and are also available in 316 SS, providing durability in corrosive and demanding plant environments. A calibrated ruler option is available for accurate level measurement at a glance, further reducing the need for secondary instrumentation.
Available Configurations and Materials
Jogler manufactures the level style indicator in multiple configurations to suit a wide range of process fluids, pressures, and installation requirements.
Single-Tube Models
The single-tube liquid level indicator provides a direct, unobstructed view of the process fluid. It is well-suited for standard liquid service where a single transparent tube offers sufficient safety and visibility.
- Model LS — Single Tube
- Model ULSS — FEP Teflon-Lined Single Tube
Tube-in-Tube Models
The tube-in-tube liquid level indicator adds an outer protective tube around the inner sight tube, providing an additional layer of containment and safety. This configuration is recommended for applications involving hazardous or high-pressure fluids.
- Model LT — Tube-in-Tube
- Model ULTS — FEP Teflon-Lined Tube-in-Tube
Side Connector Materials
Side connectors are available in the following materials to match your process requirements:
- Powder-coated carbon steel
- 316/316L stainless steel
- PTFE Teflon-lined carbon steel
Sight Tube Materials
Sight tubing materials include borosilicate glass, polycarbonate, acrylic, and FEP Teflon to provide the appropriate chemical compatibility and mechanical strength for your application.
Long Lengths, Minimal Joints
Each gauge section is available in lengths up to 10 feet, significantly reducing the number of joints required compared to conventional multi-section sight glass assemblies. Fewer joints mean fewer potential leak points and a simpler, more reliable installation.
Shipped fully assembled, Jogler level style indicators make field installation straightforward without the need for complex on-site fabrication.
