PRODUCT DESCRIPTION
Fully Automatic Thermostatic Petroleum Density Meter U Shaped Data
Storage 80 Groups
The SH102D Fully Automatic Thermostatic Petroleum Density Meter is
applicable for determining the density and relative density of
liquids. It works on the principle that a dual U-shaped tube
exhibits distinct vibration frequencies when filled with different
media. The meter complies with the standards of GB/T2013-2010,
GB/T29617-2013 and ASTM D 4052. After the liquid sample is pumped
into the resonant cylinder sensor, a single-chip microcomputer
processes the measurement data, ensuring rapid, direct and highly
sensitive results. The device consists of a dual tuning fork
density sensor, an oscillation cylinder circuit, a temperature
measurement circuit, a CPU, a display unit, a thermostatic bath, a
liquid inlet pump and a control panel. It is widely used for
density measurement of various liquids. Equipped with dedicated
concentration conversion software, it can directly read the
concentration values of specific liquids, such as alcohol. With
single-chip software processing, it can display volume
concentration data directly, making testing operations more
convenient.
This U-tube oscillation densitometer conforms to the international
standard ISO 12185:1996 Determination of Density of Crude Oil and Petroleum Products -
U-shaped Vibrating Tube Method, as well as the industry standard SH/T0604-2000 Determination of Liquid Density and Relative Density (Digital
Densimeter Method).
Working Principle of U-Tube Oscillation Densitometer for Liquid
Density Measurement
The oscillation tube method measures substance density by using an
electromagnetically driven U-shaped glass tube to generate
oscillations. The vibration frequency of the tube is correlated
with the density of the filled substance. The actual density of the
measured sample is calculated by analyzing the frequency difference
between the sample and a reference standard substance. This
oscillation tube method ensures high measurement accuracy.
Performance Features
- Thermostatic Control: Liquid density is highly temperature-dependent, so it is
necessary to convert the density measured at real-time temperature
to the standard density at 20°C. This instrument adopts
thermostatic bath control, enclosing the sensor, its components and
the sample liquid in a thermostatic chamber. A temperature sensor
monitors the temperature of the oscillation tube and sample liquid.
The single-chip microcomputer controls electronic components to
cool or heat the chamber, maintaining the temperature within 20°C ±
0.1°C. This eliminates the hassle and errors caused by manual
temperature conversion, and ensures the instrument's measurement
accuracy, stability and repeatability (the constant temperature can
be customized according to user requirements).
- Direct Display of Density at 20°C with Temperature Readout: The single-chip microcomputer detects the sensor's oscillation
frequency, applies a mathematical model of the relationship between
sensor frequency and liquid density to calculate the density value,
and performs floating-point operations to avoid errors caused by
insufficient calculation digits. The calculated density value is
displayed as a 5-digit number, with a dedicated temperature display
window.
- Automatic Sampling: A single-chip microcomputer controls a stepper motor to drive a
peristaltic pump for sample aspiration, enhancing the product's
automation level.
- Acid and Alkali Resistant Tubing: All tubing in direct contact with the liquid is made of imported
acid and alkali resistant materials, enabling the instrument to
measure acidic and alkaline solutions.
- Data Storage and Transmission: Built-in memory can store 80 sets of test data, which can be
retrieved and deleted as needed. The instrument can be connected to
a computer via RS232 interface (customizable per user
requirements).
Calibration Function
Long-term inactivity may cause instrument drift. This device can be
calibrated using pure water at 20°C as the standard reference, a
function unavailable with traditional glass densitometers.
