Tubular Liquid Level Gauge
Simco Tubular liquid level gauges, are a cost effective method of visual liquid level indication for tanks operating at low pressures. The instruments consist of a toughened continuous section of boroslicate glass tube which is connected at both the top and bottom to an isolation valve. The connection between the valve and glass is sealed by means of a rubber gasket contained within a union on the valve. The isolation valves used on this type of instrument are most commonly the ‘off set’ pattern type as this allows for the gauges to be cleaned (Roddable).
