China electromagnetic water flow meter manufacturer
Henan Junyuan Automation Equipment Co., Ltd. was established in 2002 and has professional R&D, production and sales experience. Provides various flow measurement equipment, pressure, temperature and liquid level measurement equipment to Chinese and international customers. We support various customizations (including: LOGO, nameplate, brand, appearance color, size, etc.)
The principle and scope of use of the instrument:
The electromagnetic water flowmeter is a device that uses the principle of Faraday's electromagnetic induction law to measure the instantaneous flow and cumulative flow of conductive liquid passing through the pipeline. Due to its high measurement accuracy, high stability and reliability, various communications, and many other advantages, it can be connected to a variety of control equipment and is widely used in various industries such as water supply, chemical industry, food, and pharmaceuticals.
The instrument consists of a converter and a sensor consisting of two coils placed at right angles to each other. When fluid flows through a pipe, a voltage is generated that is proportional to the flow rate. The voltage is then measured via an electromagnetic sensor and the flow rate is calculated.
Main advantage one: It is not affected by the flow pressure, temperature and viscosity of the liquid being measured. The device is also easy to install and maintain, has a long lifespan and requires little maintenance or calibration.
Key advantage two: It provides high accuracy even in harsh environments such as those with sand, suspended solids and chemicals. Additionally, the device has no moving parts, meaning it is less susceptible to wear and tear, making it durable and cost-effective.
Overall, its versatility, accuracy and durability make it the product of choice for measuring liquid flow in many different industries, and its simplicity of installation and maintenance ensures it can be easily integrated into existing systems.

Lining material selection:
The lining selection of the magnetic flowmeter is very important. It is necessary to select the most suitable lining material according to the characteristics of the medium being measured, which is the key to ensuring the working stability, accuracy and service life of the instrument equipment. A brief introduction to the following most commonly used lining materials:
Rubber lining：
Application range: 0℃-80℃ non-strong acid, strong alkali, strong oxidizing medium. It can measure weakly abrasive media, water, river water, irrigation water, wastewater, sewage, paper pulp and mud and other conductive liquids.
Polytetrafluoroethylene (PTFE)：
Scope of application: -25 degrees to 140 degrees, strongly corrosive substances such as concentrated acid and concentrated alkali, and sanitary media such as drinking water, milk, beer, and beverages.
Fluorinated Ethylene Propylene (F46)：
Scope of application: -25 degrees to 100 degrees non-strong abrasive media, sanitary media.
The electrode selection of magnetic water flowmeter is very important. It is necessary to select the most suitable electrode material according to the characteristics of the liquid to be measured, such as sanitary liquid, water, containing acid and alkali, and the liquid contains solid particles (select wear-resistant materials). The following are the most commonly used electrode materials:
1.Molybdenum-containing stainless steel (316L)：
2.Stainless Steel Coated Tungsten Carbide:
3.Hastelloy electrode:
4.Titanium (Ti)：
5.Tantalum (Ta)：
Calibration time and calibration points:
All our flowmeters undergo one-to-one verification before leaving the factory to ensure 100% factory qualification rate.
Each measurement time should be no less than the shortest measurement time allowed by the device, and the shortest time should generally be no less than 30s, and for Class A instruments (electromagnetic flowmeters with frequency output, plug-in electromagnetic flowmeters with frequency output) should be Ensure that the absolute value of the relative error of the number of pulses output by the flow meter in a calibration is not greater than 1/3 of the repeatability of the flow meter being tested.
The calibration points when evaluating the performance of the instrument are generally stipulated as follows: For Class A instruments, the calibration points should include qmin, 0.07qmax, 0.15qmax, 0.25qmax, 0.4qmax, 0.7qmax and qmax. When the flow rate of the latter few calibration points is less than qmin, This calibration point can be ignored. For Class B instruments (referring to electromagnetic flowmeters that output analog signals or can directly display instantaneous flow), the calibration points should include at least 5 verification points including qmin and qmax, and be evenly distributed.
Simple production process of the instrument:
From cutting pipe---welding---electrode---lining---coil---sealing---polishing---painting---checking---packing.
