Flow density meter of liquid "QUANTOR-501"

The QUANTOR density meter is designed to automatically measure the density and temperature of a liquid.
The QUANTOR-501 density meter is designed to work in systems of automatic control, regulation and control of technological processes for measuring the density and temperature of a liquid in a static state and flow.
The density meter "QUANTOR-501" is produced according to TS 4318-004-44952701-2021.
Scope of application – automated control and accounting systems, regulation and control of technological processes.
The measurement results can be displayed on the operator panel screen in digital and graphical form.
Additional functions:
arrangement of reports
transmission of measurement results via the LoRa channel
access to measurement data via a PC browser
integration with mobile applications via a density meter Wi-Fi access point
sending measurement results via GSM network to the monitoring server
transmission of measurement results via the 4-20 mA current loop interface
The density meter is used to measure the density of the following liquids:
commercial oil
light oil products
dark oil products
The density meter is installed on the pipeline. It can be used as part of mass accounting systems and determination of the quality of liquids at the facilities of the oil refining, food and chemical industries.
The high accuracy of density measurement allows the device to be used for monitoring almost any commercial and technological operations.
other liquids
The built-in digital interface allows the device to be integrated into automated process control systems and eliminates the need for manual measurement
Built-in diagnostic and calibration tools
Maximum measurement accuracy provided by the vibrational density measurement method
Mobile software
The application ensures:
sensor calibration;
monitoring of liquid density and temperature readings;
The smartphone connects to the density meter via its Wi-Fi access point. Calibration parameters are stored in the device memory.
