Doweston is a professional flow meter manufacturer with a wide range of product types, including electromagnetic flow meter, Vortex flow meter, thermal flow meter, etc., to meet the needs of flow meter in different industries and occasions.

1. electromagnetic flow meter

Electromagnetic flow meter is a commonly used flow meter that can be used to measure the flow of conductive liquids and liquid solid particles. The principle is to use Faraday's law of electromagnetic induction to calculate the liquid flow rate by measuring the electromotive force induced by the magnetic field. Electromagnetic flow meter are widely used in water treatment, chemical industry, metallurgy, environmental protection and other fields.

Doweston's electromagnetic flow meter has the characteristics of high precision, strong reliability, wide adaptability and easy maintenance. The company's electromagnetic flow meter are divided into two categories: intelligent electromagnetic flow meter and remote electromagnetic flow meter.

Intelligent electromagnetic flow meter can realize digital signal processing, multiple output modes, multiple communication protocols and other functions. This flow meter is suitable for occasions with high measurement accuracy and large flow changes, such as chemical industry, petroleum and other fields.

The remote electromagnetic flow meter is an online remote monitoring system that can transmit measurement data to the cloud platform through GPRS, CDMA and other communication methods to achieve remote monitoring. This flow meter is suitable for remote monitoring, data collection and other occasions, such as urban water supply, water conservancy projects and other fields.

2. vortex flow meter

Vortex Flow MeterIt is an instrument for measuring liquid flow. It calculates the flow rate by measuring the rotation angular velocity generated by the fluid passing through the turbine. This flow meter is suitable for flow measurement of liquids, gases, steam and other media, and is widely used in chemical industry, food, pharmaceutical and other fields.

Doweston's Vortex flow meter has the characteristics of high precision, strong reliability and good anti-interference performance. The company's Vortex flow meter are divided into two categories: intelligent Vortex flow meter and Vortex flow meter transmitters.

The intelligent Vortex flow meter adopts digital technology and has functions such as digital filtering and multi-point linear calibration, which can effectively improve measurement accuracy and stability. This flow meter is suitable for applications requiring high measurement accuracy and reliability, such as petrochemical, pharmaceutical, electric power, food and other industries.

The Vortex flow meter transmitter is a device that converts the electrical signal generated by the sensor into a standard signal output. This product can be used in conjunction with the Vortex flow meter sensor to output a 4-20mA current signal, enabling remote transmission and control. This product is widely used in flow measurement fields such as liquids, gases, and steam.

Doweston's Vortex flow meter also have many innovations in design and manufacturing. For example, the company uses advanced CAD design technology to ensure that the product has a compact structure and high reliability; the company also has a complete quality management system and testing equipment to ensure the stability and accuracy of the product.

In addition, Doweston's Vortex flow meter are also explosion-proof, high-temperature, and corrosion-resistant. For example, the company's FV4200 Vortex flow meter is made of 316L stainless steel, which can withstand high temperatures and corrosion; the company's FT5200 Vortex flow meter can reach ExdIICT5 explosion-proof level.

In addition to electromagnetic flow meter and Vortex flow meter, Doweston also produces mass flow meter, gas ultrasonic flow meter, liquid ultrasonic flow meter, thermal gas mass flow meter, etc.

Among them, the mass flow meter is a high-precision flow meter suitable for gas and liquid flow measurement. It can measure the quality of materials flowing through the pipeline without considering changes in pressure and temperature. This flow meter uses a sensor to directly measure the mass of the fluid instead of calculating the flow rate through volume. Doweston's mass flow meter adopts advanced technologies such as thermal sensors and pressure sensors, and has the characteristics of high precision and good stability.

Gas ultrasonic flow meter is a flow meter suitable for gas flow measurement. It uses ultrasonic technology to measure and calculate the flow rate by measuring the speed and direction of ultrasonic waves propagating in the fluid. Doweston's gas ultrasonic flow meter adopts technologies such as time difference method and Doppler effect, and has the characteristics of high accuracy and no maintenance.

Liquid ultrasonic flow meter is also a flow meter that uses ultrasonic technology for measurement and is suitable for liquid flow measurement. This flow meter adopts Doppler effect, acoustic wave interference and other technologies, and has the characteristics of high precision and no maintenance.

Thermal gas mass flow meter is a flow meter suitable for gas flow measurement. It calculates the flow rate by measuring the temperature difference generated by the fluid on the thermal sensor. This flow meter adopts thermal sensor and temperature compensation technology, which has the characteristics of high precision and good stability.
