IBR-11B Bronze Sleeve Packed Water Level Gauge

Overview

An IBR-approved bronze sleeve packed water level gauge with screwed BSP parallel threaded ends, designed for water and steam service. Features an automatic shut-off device in the water arm, available in right-hand or left-hand orientation. Standard pattern bronze body construction rated for moderate pressure boiler-adjacent applications up to 225°C. A test certificate in Form III-C as per IBR is furnished with every supply, sized and serviced for boiler plants across Nepal.

Features & Benefits

• ✓Bronze body construction offers strong corrosion resistance in boiler feedwater and steam condensate service, while being lighter and generally more cost-effective than the cast steel CS-6 variant for moderate pressure applications.
• ✓Automatic shut-off device in the water arm closes off flow if the sight glass breaks, preventing uncontrolled steam or hot water discharge — the same critical safety mechanism as the cast steel version, here in a bronze body suited to lower pressure boilers.
• ✓Screwed BSP parallel threads to BS 21 give a precise, standardized thread fit that simplifies sourcing replacement fittings and ensures consistent sealing across different installations.
• ✓IBR Form III-C certification supplied with every unit qualifies this gauge for use on regulated steam boiler installations in India, same compliance benefit as the cast steel CS-6 but at this gauge's lower 250 Psig pressure class.
• ✓Right hand / left hand orientation lets the same product mount correctly on either side of the boiler without a mirrored special order.
• ✓Sized from 10mm to 20mm, this gauge targets smaller boiler and vessel connections compared to the CS-6, which is the appropriate choice when the mounting boss is smaller or pressure requirements are below 250 Psig.
