Product Categories and Applications
The company’s product portfolio spans nine categories: flow, pressure, level, temperature, valves, calibrators, recorders, analyzers, and switches. These instruments are widely used in petroleum, chemical, papermaking, water treatment, municipal engineering, food processing, power generation, steelmaking, coal, pharmaceutical, and environmental protection industries. Below, we highlight key instruments and their specific applications.
Flow Measurement Instruments
Electromagnetic Flow Meter: This instrument is ideal for measuring water flow in water projects, sewage treatment plants, the pulp industry, and flocculating agent factories. It offers high accuracy and reliability in conductive fluids.
Vortex Flow Meter: Best suited for measuring steam flow rate, this meter is majorly used in power plants and supply heating industries. Its robust design handles high temperatures and pressures.
Thermal Mass Flow Meter: Designed for measuring compressed air, natural gas, and biogas flow rates, this meter is essential for energy management and emission monitoring.
Multi-Variable Differential Pressure Flow Transmitter: This device is used with throttling elements like V-cone, orifice plate, Verabar, nozzle, and Venturi to directly display instant flow rate and total flow. Flow units include M3, Ton, and MMSCFD.
Wall-mounted Doppler Open Channel Flow Meter: Used to measure flow velocity and calculate flow rate in sewage pipes (chemical wastewater, pre-treated wastewater, wastewater after initial treatment), total stormwater pipes, and irrigation channels. It works with standard weirs or flumes, such as triangular weir, rectangular weir, and Parshall flume.
Level Measurement Instruments
Radar Level Meter: Suitable for measuring liquid level (water, oil, chemical liquid) in storage tanks, as well as powder or grain particle silos. Non-contact measurement ensures minimal maintenance.
Magnetic Level Indicator: Used for liquid level measurement in storage tanks for water, oil, and chemicals. It can be configured with a level transmitter for analog current signal output or with non-hold/hold type level switches for control or alarm.
Pressure and Temperature Instruments
Pressure Transmitter: Widely used in the chemical industry to measure process pressure. Rugged construction ensures long-term stability.
Temperature Transmitter: Often paired with temperature sensors for accurate temperature monitoring in various processes.
Certifications and Quality Assurance
Jiangsu Hongguang’s commitment to quality is reflected in its certifications. The company holds ISO 9001:2015 for quality management, ISO 14001:2015 for environmental management, and ISO 45001:2018 for occupational health and safety. Additionally, several products have SIL certification: ultrasonic level meter, magnetic level indicator, electromagnetic flow meter, metal tube rotameter, radar level meter, pressure transmitter, temperature transmitter, and tuning fork level controller. This certification is crucial for safety-critical applications in industries like oil and gas.
