Overview
In response to the emergence of numerous new liquid level meter products and technologies, which have exposed issues such as low accuracy and inconvenient installation methods in existing liquid level meter calibration devices, our company has conducted extensive research on the working environment of liquid level meters, the current state of liquid level meter products, and existing calibration conditions and methods. Integrating these findings with the requirements of the domestic market for liquid level measurement equipment, Hengsheng Weiye has developed a comprehensive calibration system for liquid level gauges.
The HSIN8000 series real standard method liquid level meter calibration device is specifically designed for the verification of liquid level instruments. It integrates software and electrical measurement into one system, providing precise measurement and control of liquid levels to meet the requirements of automatic detection. This device is widely used in various calibration laboratories and metrological testing institutes.

Technical Parameter
1. Main Structure:
– Constructed entirely from stainless steel, with anti-corrosion treatment on the liquid contact and sealing parts, and smooth surface treatment to prevent scratching and oil residue.
– Comprises a measuring cylinder, water tank, and cabinet.
2. Measuring Cylinder:
– Made from 304 stainless steel with a process connection top mounting flange, customizable based on customer requirements.
– Easy to install, capable of bearing up to 50kg.
– Mechanical levers can be extended to human standing height during loading and unloading inspections, avoiding climbing hazards and space limitations.
3. Water Tank:
– Food-grade plastic, no load weight 10kg, full weight 200kg.
4. Control Cabinet (Optional):
– Integrated placement of host, display, control, and data acquisition components.
5. Vertical Positioning Parts:
– Ensures vertical calibration during installation to maintain verticality post-installation.
– Limits the ends of the measuring cylinder under test conditions to ensure alignment with the main standard.
– Uses different limiting tools based on the installation type of the instrument under test.
6. Control System:
– Independently developed control processor for accurate liquid level control.
– After installation, the liquid level is automatically controlled to the preset detection point without additional operations, eliminating the need for complex fine-tuning steps.
– Controls inlet and drainage valves to bring the liquid level near the preset value, then uses a fine-tuning module to achieve the final liquid level, ensuring precise measurements.
7. Control Processor:
– Powered by 220V AC, peak power consumption 2000W, used with control software.
8. Software:
– Enables automatic measurement of preset parameters.
– Facilitates automatic collection, analysis, calculation, and display of measurement data.
– Generates and prints records and reports.
– Provides real-time status information on current measurements.
Calibration
HSIN8000 can calibrate kinds of liquid level instrument such as liquid level meter/transmitter (magnetic flap/Magnetostrictive/capacitive, input, RF/vibration/tuning fork/ultrasonic/guided wave radar, steel strip/glass tube/glass plate/external sticker/window type, buoy/float/float type, etc.)
