STAND FOR CALIBRATION AND PRIMARY VERIFICATION OF FLOW DENSITY CONVERTERS Russian patent published in 2024 - IPC G01N9/24 G01N9/10 G01N9/02 

FIELD: measuring equipment.

SUBSTANCE: bench for calibration and primary verification of flow converters of density of oil and oil products contains automated workstation of operator for processing and registration of measurements and measuring circuit. Measuring circuit consists of interconnected by means of pipelines of temperature control system with pipeline of temperature control system, gear pump connected by thermally insulated pipeline with flow and pressure regulator, which is connected by said thermally insulated pipeline with pressure setter, five tanks intended for flushing fluid and working fluid, as well as a drain tank, a filter, a reversible pump, a thermally insulated cabinet with an air conditioning system. Thermally insulated cabinet contains connected to each other by a thermally insulated pipeline with ball valves and valves a filter, temperature converters and pressure converters, each of which is provided with local indication in thermal cases, a pycnometer unit in a thermal case, containing two pycnometers and three flow density converters: reference and two working ones, located in thermal blocks of reference and working flow density converters, rotameter and four heat exchangers.

EFFECT: possibility of confirming reliability of metrological characteristics of flow density converters in the working fluid temperature range from -15 to +50 °C, improved quality of control and verification to the level of modern metrological requirements and reduced time for verification and calibration of working flow density converters.
