1. Product Overview:

Electromagnetic flowmeter (EMF) was developed rapidly in the 1950s and 1960s with the development of electronic technology

A rapidly developing new type of flow measurement instrument. An electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the induced electromotive force when the fluid passes through an external magnetic field.

2. Product features:

The linear measurement principle can achieve high-precision measurement without being affected by changes in fluid density, viscosity, temperature, pressure, and conductivity; ★ There is no obstruction or moving parts in the measuring tube, and the pressure loss is small, so it will not cause additional energy loss or blockage, and the energy-saving effect is significant. It is particularly suitable for measuring liquid-solid two-phase flow media such as sewage, mud, slurry, pulp, etc. ★ Low installation requirements, the front straight pipe section only requires 5D, and the rear straight pipe section is 2D (D is the inner diameter of the selected instrument)

Product Overview

UF-E dual rotor flowmeter (hereinafter referred to as flowmeter) is a new type of volumetric flowmeter with unique design and precision machining assembly. A pair of spiral rotors are the moving bodies inside the measuring chamber, playing a role in dividing, measuring, transporting, and excreting the measured liquid. This model of flowmeter has added positioning gears in its structure, so that the two rotors do not come into contact with each other when rotating. This flowmeter operates smoothly, with low noise, minimal wear, high accuracy, and strong viscosity adaptability, allowing fine particles in the measured liquid to pass through without easily getting stuck. This flowmeter has undergone chemical nickel plating treatment, thus possessing anti-corrosion and wear-resistant properties, and can replace stainless steel flowmeters.

Product Features

Suitable for thin oil, light oil, heavy oil, crude oil with high sand content and high water content, with a wide viscosity range of the measured liquid.

The flow meter passes through a large liquid flow rate, which is about twice that of a regular volume meter with the same diameter.

Long service life, high accuracy, and strong reliability.

The internal pressure loss is extremely small.

◆ Wired remote transmission * * * Long distance of 1000 meters, pulse signal output N=0.1L (one pulse is 1N), can be directly connected to a computer network.

◆ Intrinsic safety explosion-proof type Ia Ⅱ CT4 (intrinsic safety type); IP65 protection.

2. For a flowmeter with an accuracy level of 0.2, the upper limit of the flow range remains unchanged, and the lower limit is calculated based on a scale ratio of 1:5. For an accuracy level of 0.1, it is calculated based on a scale ratio of 1:3.

Electromagnetic flowmeter is currently one of the most widely used applications for fluid flow measurement in the market. It is precisely because of its wide range of applications that it is suitable for different media and process scenarios, with corresponding functional parameters and material properties. Therefore, our manufacturers have corresponding electromagnetic flowmeter models for such situations, so there are many types of electromagnetic flowmeter models, and many users have only a partial understanding or even a blank face about the models. Below, the editor has compiled a basic list of all electromagnetic flowmeter models and their meanings.

The above is a complete list of conventional electromagnetic flowmeter models, including their meanings, but not all models. If you need to consult the parameters of electromagnetic flowmeter models, you can consult our sales team. However, the editor here gives a suggestion to users not to use the model as the selection standard. After all, the model is set by people. Once the model is set incorrectly or certain specific models cannot be found, there will be errors in selecting the product or price that you want, and even affect the production process operation on site. Therefore, when choosing electromagnetic flowmeters, users should try not to follow the electromagnetic flowmeter model as the standard. Please provide detailed on-site process parameter requirements, so as to ensure that the selection of electromagnetic flowmeters suitable for the site is maximized, and unnecessary costs can be avoided for future operation. Excuse me.

Take one of the electromagnetic flow meters as an example! The principle of his operation measurement is actually known to us in middle school, which is the principle of electromagnetic induction. It is widely used for precise measurement in various industries, but mainly for measuring the total amount of conductive liquids. Overall, this electromagnetic flowmeter is quite good.

***Afterwards, I would like to say that Huayun Instrument Company is truly dedicated to making products, and I hope and thank our customers for choosing Huayun Instrument's electromagnetic flow meters and other products. You won't lose out on what you buy, and it will be more practical and easy to use.
