Installation Versatility—With the integration of a wafer-style liquid level sensor and transmitter into one product, the L3 enables users to install pneumatic level controllers to a variety of industry standard or custom process vessel connections. Installing the L3 in a customer-supplied external cage gives process equipment designers freedom to select the best process vessel connection location and configuration to meet specific application requirements.
Easy Adjustment—Set point and proportional valve opening are made with simple dial-knob controls.
Simple, Durable Construction—Few moving parts are used. Knife-edged driver bearing in sensor and plated brass instrument case ball bearing for torque tube rotary shaft help provide low-friction operation.
Easy Reversibility—Action is field reversible from direct to reverse or vice versa without additional parts.
Reduced Maintenance Costs—Spring-out wire provides for in-service cleaning of relay orifice.
Reduced Operating Costs—Supply pressure conservation is enhanced because relay exhaust opens only when output pressure is being reduced.
NACE Compliant— The materials used in the L3 wafer-style sensor meet the metallurgical requirements of NACE MR0175-2002. Environmental limits may apply.
