HOLYKELL offers a diverse range of flowmeter products, including ultrasonic, radar, electromagnetic, positive displacement, mass, vortex, and turbine flowmeters. Ultrasonic flow meters are ideal for clean, single-phase liquids in applications like factory effluent and sewage treatment. Radar flow sensors provide non-contact measurements for rivers, irrigation canals, and flood control. Electromagnetic flowmeters are designed for conductive liquids, with various types to suit different applications. Volumetric Flow Meters are used for measuring expensive and high-viscosity media. Tri-rotor flow meters are widely used in crude oil and refined oil trade settlements. The MDR-E dual rotor flow meter boasts precision design and assembly. Mass flow meters directly output mass flow and can measure most liquids and gases. Vortex flowmeters are ideal for industrial pipeline fluids like gas and steam. Turbine flowmeters find application in petroleum, organic and inorganic liquids, and cryogenic fluids. Roots Flow Meter is precise and suitable for continuous or intermittent liquid flow measurement. Target Flow Meter finds widespread use in petroleum, chemical, energy, and environmental industries. HEG oval wheel gear rotor flow meters measure high-viscosity media and are popular in various industries like petroleum and paper making. Lastly, the Metal tube rotometer is well-suited for small diameter, low-velocity flows with a simple structure and minimal pressure loss.
