Column level indicators are a simple, well-proven and fairly ubiquitous approach to fluid level monitoring, so it is interesting to find a new design from standard component market leaders Elesa. Their new HCK range offers polycarbonate shielding and a graduated easy to read screen as standard in window lengths from 42mm to 452mm.
The HCK-GL variant addresses the special needs of equipment using glycol-based solutions with the added protection of a polycarbonate shielded pyrex sight glass. This is suitable for applications with glycol-based coolant and heat transfer agents – especially in sub-zero environments, for example anti-freeze, but also for example in production of polymer precursors, hydrate inhibition and other specialist niche processes.
Elesa offers an extensive range of special versions for the column level indicators such as a red float, black float with stainless steel spiral, greater length sight glasses, pre-set electric sensors, packing rings, built-in thermometer, external thermometer with probe, electric level sensor and special screw with nickel-plated brass top fitted to the lower assembly for maintenance operations.
