Level measurement
Continuous level monitoring and limit alarms in tanks, hoppers and process vessels.
Gamma source holders
Gamma source holders (BGI) are radiation-shielding housings for sealed Cs-137 gamma sources used inside industrial radioisotope instruments.
BGI source holders form a directed radiation beam through a slit or conical aperture and are deployed in level gauges, density gauges, gamma relays and non-contact process-monitoring systems.
JSC Kvant manufactures the BGI-A range for IGI-Ts sources and performs loading, reloading, supply and lifecycle support in line with radiation-safety requirements.
