The MG9400 Series Nozzle Flowmeter is a high-performance flow measurement device engineered for harsh industrial conditions. It stands out with high-temperature & high-pressure resistance, impact resistance, wide measurement range and high measurement accuracy, making it ideal for measuring single-phase and some mixed-phase flows of liquids, steam and gases. With a robust structure and cost-effective design, this flowmeter has become a reliable choice for sectors like petroleum, chemical, metallurgy, electric power and light industry. It features dual-chamber housing and factory sealing, ensuring stable performance and long service life even in extreme environments.

The flowmeter has asimple and robust structure that resists impact and corrosion, leading to an extended service life and lower maintenance costs. Its wide applicability covers various media, including high-temperature and high-pressure steam and water, which are common in heavy industries.
As a standard throttling device, it can be put into use without actual flow calibration, saving time and labor costs for on-site installation and commissioning. This advantage is especially valuable for urgent industrial project deployment.
The intelligent standard nozzle version can simultaneously display cumulative flow, instantaneous flow, pressure and temperature, providing comprehensive data support for industrial process control. It also reaches a maximum operating pressure of 42MPa, meeting the needs of high-pressure working conditions.

In chemical plants, theMG9400 Series Nozzle Flowmeter is used to measure the flow of high-pressure chemical raw materials and reaction intermediates, ensuring precise control of production processes. For petroleum refineries, it monitors the flow of crude oil, refined oil and high-temperature steam in distillation units, helping to optimize energy consumption and production efficiency.
It is widely applied in thermal power plants to measure the flow of boiler steam and cooling water. The high-temperature and high-pressure resistance enables stable operation under the harsh conditions of power generation systems, providing accurate data for load adjustment and energy-saving management.
In food and beverage factories, the flowmeter measures edible liquids such as syrup, milk and beverage raw materials, with food-grade material options available to meet hygiene requirements. For pharmaceutical production, it is used to monitor the flow of pharmaceutical intermediates and purified water, ensuring compliance with strict production standards.
In metallurgical enterprises, it measures cooling water and compressed air flow in smelting processes, supporting equipment cooling and process optimization. For water treatment plants, it monitors the flow of raw water and treated water, helping to control the dosage of chemicals and ensure treatment efficiency.
It is particularly suitable for high-temperature and high-pressure steam and water, and can also measure various gases and liquids, including single-phase and some mixed-phase flows.
No. As a standard throttling device, it complies with ISO-5167 and GB/T 2624-2006 standards, and can be used directly without actual flow calibration.
The maximum operating pressure reaches 42MPa, which can meet the requirements of most high-pressure industrial working conditions.
