Digital Tuning Fork Density Meter – XY-886 Vs SITAN MP43-YMD

When choosing a Digital Tuning Fork Density Meter, you should consider the features and price. There are two main options: the XY-886 and the SITAN MP43-YMD. These models offer several advanced features and benefits. In this article, we will compare these two options.

XY-886

The XY-886 is a new product that uses a high-precision vibratory principle to detect fluid density. It has a plug-and-play installation and is widely used in pipelines and open tanks. Its unique design includes a transmitter and a vibrating fork body. The vibration period varies with the density of the liquid being measured. The meter’s measurement accuracy is accurate to within a few ppm, and it also has a built-in temperature sensor.

The XY-886 is manufactured with a high-quality gold-plated transducer that is imported from Germany. This high-grade gold-plated transducer provides excellent linearity, long life and low temperature drift. Its ceramic cross-gold base plate ensures good contact with the transducer. The frequency range can be adjusted up to 1000 Hz, and the instrument has a ring-shaped vibration isolation system to reject mechanical vibration.

The tuning forks are made with high-grade, precision materials, which ensure uniformity of accuracy and repeatability. The tuning forks are also sandblasted to ensure durability and mechanical strength. The tuning forks used by Emerson are made with full-set Japanese core modules. Emerson’s products have an outstanding cost-performance ratio.

A vibration type density meter uses a mechanical oscillator with a resonance frequency that varies with the density of the specimen fluid. The resonator is cylindrical in shape and has flanges on both ends. One end of the resonator is open to allow the specimen fluid to be introduced. The resonator is connected to a cover that is coupled to the flanges. A circuit means is provided for processing the frequency signal and displays the density of the specimen fluid.

To expand the exactness of on-line fluid thickness estimations, a sensor furnished with a tuning fork as the resounding delicate part is planned in this paper. It is a semi computerized sensor with basic construction and high accuracy. The sensor depends on reverberation hypothesis and made out of a delicate unit and a shut circle control unit, where the delicate unit comprises of the actuator, the thunderous tuning fork and the finder and the shut circle control unit involves precondition circuit, computerized signal handling and control unit, simple to-advanced converter and computerized to-simple converter.

Vibrational element density meters are also known as mass flow meters or inertial flow meters. They measure the phase shifts of a thin-walled tube as it rotates about its central axis. When there is no mass inside, the section remains untwisted. However, when a mass is present inside, the mass will cause the section to twist, affecting its resonant frequency. This resonant frequency directly affects the density. For example, a higher-density fluid will produce a larger Coriolis effect than a lower-density one.

The resonant frequency of the tuning forks is an important parameter in density measurements. The lower the resonant frequency of the tuning forks, the lower the density measurement accuracy. This property of the forks makes it possible for the resonant frequency to be adjusted in order to decrease the partial influence of viscosity.

SITAN MP43-YMD

The SITAN MP43-YMD Digital Tuned fork density meter uses a tuned tuning fork to measure the density of oil. It has a temperature-controlled digital sensor and an optional media temperature of 0100 or 0150 degrees Celsius. The unit is primarily composed of a transmitter and an aluminum alloy shell.

The tuning fork as a sensitive component works on the resonance principle and has excellent sensitivity in measuring liquid density. The compact, light weight, and simple structure allow for accurate measurement. Its dynamic principle also enables it to analyze the natural frequency of the tuning fork and the effect of temperature, position, and structural parameters. This device has a high precision and repeatability, averaging an error of less than 0.03%.

The tuning fork is placed in the liquid measurement chamber and vibrates in accordance with its natural frequency. As the tuning fork contacts the liquid, its mass changes, causing the frequency of the vibration to change. This signal is picked up by a detector, which converts the signal to a density value.

The resonant frequency of a fork density meter is directly related to the mass of the sample. Since this frequency increases with temperature, it’s important to maintain an accurate temperature in the measurement room. For accurate measurements, modern density meters must be equipped with efficient temperature control. Even a temperature difference of one degree can affect the density of a sample by as much as 0.1-0.3 kg/m3.

The resonant frequency principle of a fork density meter is a relatively simple one. The basic idea is the same as in the ultrasonic method. The resonant frequency of a tuning fork is affected by the density of the liquid, and the higher the density, the lower the resonance frequency. Changing the tuning fork structure can reduce this effect.

An estimated boundaries model of the tuning fork is laid out and the effect of fluid thickness, position of the tuning fork, temperature and underlying boundaries on the regular recurrence of the tuning fork are additionally broke down. On this premise, a tuning fork fluid thickness estimation sensor is created. What’s more, trial testing on the sensor has been done on standard alignment offices under consistent 20 °C, and the sensor coefficients are adjusted. The trial results show that the repeatability mistake is around 0.03% and the exactness is around 0.4 kg/m3. The outcomes likewise affirm that the technique to build the exactness of fluid thickness estimation is plausible.

A fluid thickness estimation sensor with the tuning fork as the delicate part, which depends on the reverberation rule, is portrayed in this paper and created to gauge thickness of fluids, static or moving. It can gauge fluid thickness straightforwardly, being a semi computerized sensor, which not just has basic design, little size, light weight, yet additionally has high accuracy and unwavering quality.

As indicated by the unique standard, an estimated boundaries model of the tuning fork is laid out, and the effect of primary boundaries, temperature and fluid on the regular recurrence of the tuning fork are likewise investigated either hypothetically or by recreation, alongside trial results that showed the better presentation of the sensor to gauge fluid thickness.

The tuning fork fluid thickness estimation sensor puts the tuning fork driven by electromagnetic or piezoelectric technique in the estimating chamber, and afterward the actuator communicates exchanging power to the tuning fork to cause it to vibrate as per its normal recurrence. While the tuning fork contacts with the fluid estimated, the additional mass of the tuning fork changes, and results in vibration recurrence (vibration cycle) changes.

The locator gets the vibration sign to recognize the vibration recurrence. By estimating the progressions of the normal recurrence or vibration cycle, the thickness of the fluid tried still up in the air. In this way, it is vital to acquire the regular recurrence of the tuning fork precisely to guarantee the brilliant exhibition of the sensor.
