Series 5200B floor mounted cabinet gas feeders are vacuum operated, solution feed, differential pressure-regulated feeders available with either manual or automatic control. The floor-mounted gas feeder is enclosed in a corrosion-resistant Polystyrene cabinet. Six different flowmeter capacities ranging from 1000 to 10,000 lb/day (20 kg/h to 200 kg/h) provide versatility in meeting gas flow requirements. Manual Series 5210B gas feed systems consist of a cabinet, vacuum regulator and an ejector, or chemical induction unit. When automatic control is required (Series 5240B) the CAPITAL CONTROLS® automatic valve, responds to control signals from a flowmeter or a PLC. If residual or flow plus residual control is needed, the CAPTROL® Model 1451 controller is used. The cabinet mounted controller receives signals from a water flow transmitter and/or chlorine residual analyzer. If multiple feed points are required, flow meter assemblies and additional ejectors are available.
