Flow meter

(1) Digital signal output The output of the turbine flowmeter is a pulse digital signal proportional to the flow rate. The advantages are easy to accumulate and easy to send into the computer system. Pulse output type: ①-General working voltage: +12VDC or +24VDC two kinds (the power supply must be selected before ordering). ②Signal transmission […]

The conductivity of liquid metal is several orders of magnitude higher than the conductivity of the best non-metallic conductive liquids. The appearance of the skin effect makes the edge effect of the magnetic field more complicated, and the influence of the eddy current becomes greater when the flowmeter with AC excitation is used. It can

Key points of customization of differential pressure flow meters: The design and customization of the differential pressure flowmeter are to determine the various parameters of the differential pressure flowmeter according to the on-site process conditions. When customizing a differential pressure flow meter, you should first determine that the fluid conditions meet the following requirements: (1)

Advanced electromagnetic flowmeter manufacturers, aiming at slurry fluid measurement and high-speed responsiveness, apply advanced semiconductor components and single-chip computer technology, and develop various high-frequency rectangles relative to low-frequency (1/8 to 1/32 power frequency) Wave excitation (usually around 100Hz, medical blood flow meter measuring human body up to 400Hz) and programmable pulse width excitation electromagnetic flowmeter,

AC excitation usually refers to the use of a 50Hz (or 60HZ) sine wave power frequency city excitation sensor. The most important advantage of this excitation method is that it can reduce the polarization of the electrolyte liquid on the electrode. Therefore, the influence of drifting DC interference on the measurement is greatly reduced. Secondly,

We know that metal conductors and conductive fluids in an alternating magnetic field will also generate an induced electric potential like the iron core of an energized iron core coil, and an induced current will appear. These induced currents flow in a vortex around the center of the conductor in the metal conductor and fluid,

Due to the cohesion between molecules, the free surface of the liquid shows a tendency to shrink. Since cohesion can only be manifested in the range of action with a small radius (approximately 10-7cm), molecules with a large distance from the interface will be offset by the gravitational forces of the surrounding molecules and will

The electromagnetic flowmeter consists of a sensor and a converter. Due to the characteristics of the principle and structure, the sensor has the following main advantages: (1) The structure is simple, there are no moving parts and disturbing parts or throttling parts that hinder the flow of the measured medium, and there will be no

Ultrasonic flow meters are divided into mono and multi-channel. If it is mono, the price is relatively cheap, but the accuracy is not high. This is the disadvantage of the ultrasonic flow meter: (1) The temperature measurement range of the ultrasonic flowmeter is not high, and generally, it can only measure the fluid whose temperature
