Flow meter

Dimethyl terephthalate (DMT) is a medium with complicated process operations and physical properties. Its particularity is shown in: (1) The process is intermittent feeding; (2) The operating temperature is around 165℃ all year round, and the highest is 195℃; (3) When the temperature is higher than 145℃, the density is about 1.065g/cm3, When the temperature […]

Most of the liquefied gas is stored in spherical tanks. The conventional measurement method uses a glass plate level gauge installed on the spherical tank or a manual gauge to measure the volume, and then calculate the mass based on the density value measured by offline sampling. Regardless of whether you use a glass plate

Since the flow rate range of liquid and gas is very different, the frequency range is also different. In the amplifier circuit that processes the vortex signal, the circuit parameters of the filter are different. Therefore, the same circuit parameter cannot be used for different measurement mediums. When the medium changes, the circuit parameters should

High-viscosity liquid medium refers to liquids with high viscosity such as crude oil, heavy oil, and residual oil. In the past, volumetric flowmeters were mostly used to measure this type of liquid, and some other flowmeters such as target flowmeters were also used, but these flowmeters directly measured the volume of the liquid, not the

Structurally, the sensor and converter form a whole, which is called an integrated electromagnetic flowmeter. The integrated electromagnetic flowmeter can reduce excitation and signal transmission cables during installation and use, save installation costs, and bring convenience to on-site operation and on-site instructions, and its instrument manufacturing cost is relatively low. Therefore, integrated electromagnetic flowmeters are

The oval gear flowmeter is mainly composed of a metering housing, an oval gear rotor, and transmission components. An instrument used for continuous or intermittent measurement and control of liquid flow in pipelines. The structure and working principle of the oval gear flowmeter The main mechanical measurement part of the oval gear flowmeter is the

The oval gear flowmeter measures the flow by means of a fixed volume and has nothing to do with the flow state and viscosity of the fluid. However, changes in viscosity will cause changes in leakage, and excessive leakage will affect measurement accuracy. As long as the oval gear flowmeter guarantees the processing accuracy and

The liquid measured by the turbine flowmeter is generally a low-viscosity (generally less than 15×10-6m2/s), low-corrosive liquid. Although there are turbine flowmeters for various media measurements, the measurement of high temperature, high viscosity, and strong corrosive media still needs careful consideration and corresponding measures. When the medium viscosity v is greater than 15×10-6m2/s, the meter

Advantages (1) High accuracy: gas turbine flowmeter, the full range is generally 1.0%~2.0%, and the high accuracy type is 0.5%~1.0%. Among all flow meters, it is one of high accuracy. (2) Good repeatability, generally up to 0.05% ~ 0.2%. Because of its good repeatability, high accuracy can be achieved after frequent calibration or online calibration,
