Sewage flow meter application and product features

Sewage flow meter application and product features:

Sewage meters are widely used in petroleum machinery, chemical plants, metallurgical plants, textile technology, food processing plants, pharmaceutical plants, paper mills and other industries as well as environmental protection departments, municipal management departments, water conservancy stations and other fields. Electromagnetic flowmeter is an all-round intelligent flowmeter developed and used by Jinhu Mingyu automatic control equipment with the highest level of technology at home and abroad. It is very different from old analog or non-intelligent electromagnetic flowmeters, especially in measurement accuracy, reliability and stability. , use function and service life.

The measurement principle of the sewage flow meter is Faraday's law of electromagnetic induction. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. It is mainly used to measure the volume flow in conductive liquids and slurries in closed pipes. Including acid, alkali, salt and other corrosive liquids.

First, the product features:
Measurements are not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
Non-obstructed flow components in the measuring tube, no pressure loss, low straight pipe requirements;
Series nominal diameter DN15.5 ~ DN3003. There are several options for sensor linings and electrode materials;
The converter uses a novel excitation method with low power consumption, stable zero point, and high accuracy. Flow range up to 1503:1;
The converter can be integrated with the sensor or separate type;
The converter adopts 16-bit high performance microprocessor, 2x16 LCD display, convenient parameter setting and reliable programming;
The flowmeter is a two-way measurement system with three integrators: forward total, reverse total, and total differential; it can be displayed. Zhuang, anti-flow, and has a variety of outputs: current, pulse, digital communications, HART protocol;
The converter adopts surface mount technology (SMT) with self-check and self-diagnosis functions;
The range of measurement confirms that the flow rate of the measured medium of general industrial sewage flowmeter is 2~4m/s. In special circumstances, the minimum flow rate should not be less than 0.2m/s, and the maximum should not exceed 8m/s. If the medium contains solid particles, the common flow rate should be less than 3m/s to prevent excessive rubbing of the lining and the electrode; for viscous fluids, the flow rate can be selected to be greater than 2m/s, and the larger flow rate helps to automatically eliminate sticking on the electrode. The role of stagnation will help improve measurement accuracy.
Under the condition that the quantum Q has been determined, the size of the flowmeter bore diameter D can be determined according to the range of the above-mentioned flow velocity V, and its value is calculated by the following equation:
Q=Ï€D2V/4
Q: Flow rate (m2/h) D: Pipe internal diameter V: Flow rate (m/h)
The range Q of the sewage flow meter should be greater than the expected maximum flow rate, and the normal flow rate should be slightly larger than 50 full scale of the flowmeter .

Extended reading: The flowmeter has no automatic control

A rotor is plalced eccentrically toward the cylinder in the space enclosed with the cylinder and the side paltes,and each component is precisely sdjusted and cconstructed with minimum clearance.
With centrifugal effect created when the rotor turns,the vanes inserted in cuts of the rotor continuously slide on the inner wall of the cylinder.
