Product Parameters
Description
Vortex street flowmeter is a speed flow meter based on the theory of natural vibration of fluid and piezoelectric crystal or differential capacitor as the detection component.
This product adopts unique differential technology, with isolation, shielding, filtering and other measures, to overcome the same products of poor seismic resistance, large noise, small signal data disorder and other problems, and adopts a unique detection probe packaging new technology and protective measures, to ensure the reliability of the product.
The product has three measurement types: basic type, differential pressure type and temperature and pressure compensation. The basic type measures the flow signal of single working condition, the differential pressure compensation type directly measures the mass flow, the temperature and pressure compensation can measure the temperature, pressure and flow signal at the same time, and output the standard volume flow or mass flow after compensation.
The product has two structural types of pipe type and insert type, can be displayed on site, can also be long distance transmission, each type has high temperature, high pressure, anti-corrosion, explosion-proof and other specifications, and integral and split structure, to adapt to different measurement media and installation environment.
The instrument has a series of advantages, such as wide range ratio, high accuracy, convenient installation and maintenance, and wide medium adaptability. It can be widely used in petroleum,chemical industry, metallurgy, machinery, food, paper making, medicine, as well as urban pipeline heating, water supply, gas and other industries of various low viscosity liquid, gas, steam and other single-phase fluid process measurement and energy saving management.

Technical parameters
• The structure is simple and firm, no moving parts, long service life, small pressure loss, low operating cost.
• New structural design of mechanical vibration resistance, shock resistance and dirt resistance is adopted.
• It achieve high exchangeability and versatility from the detection probe to the transport discharge path.
• The circuit adopts surface mounting process, with compact structure and high reliability.
• Set the menu according to the general operation principle, and use Chinese characters to prompt, clear and intuitive, simple to operate.
• Within a certain range of Reynolds number, the output signal is not affected by the physical properties of the changes and components of the measured medium, and the instrument coefficient is only related to the shape and size of the vortex body, so it is generally not
necessary to reciliate the instrument coefficient after replacing the accessories.
• The 12864 full dot matrix LCD display with fine low power consumption displays the
instantaneous flow and cumulative flow, and compensates the measured temperature and pressure, and the data is rich and intuitive.
• It has the multipoint linear correction function and greatly improves the measurement
accuracy. After using the high-speed algorithm of single pulse and pulse by pulse
measurement, the compression or broadening calculation is only delayed one by one time, to achieve complete real-time linear compensation, this performance reaches the world's leading level.
• The differential pressure compensation vortex street mass flowmeter can directly measure the mass flow rate, which is not affected by the medium component or the dry degree
change,and the measurement accuracy is higher.
• The temperature and pressure compensation built-in or external sensor automatically
corrects temperature and pressure, directly converting the working condition flow into mass flow or volume flow under standard state. The measurement is simple and accurate, and 12 compensation algorithms can meet almost meet all flow compensation requirements.
