Furthermore, Jiangsu Hongguang’s expertise extends to complementary instruments that often work in conjunction with DPTs. For instance, electromagnetic flow meters are ideal for measuring water flow in water projects, sewage treatment plants, and pulp industry. Vortex flow meters excel in steam flow measurement for power plants and heating supply. Thermal mass flow meters measure compressed air, natural gas, and biogas. Radar level meters measure liquid levels in storage tanks (water, oil, chemical liquid) and even powder/grain particle levels in silos. Magnetic level indicators with level transmitters or switches provide additional control. Pressure transmitters (including differential pressure types) are widely used in the chemical industry. Wall-mounted Doppler open channel flow meters serve sewage pipes and irrigation channels with standard weirs or flumes.
