HL system pump with digital constant-rate of flow is upgraded by adding the function of displaying the rotation speed of pump base on the HL constant-rate of flow pump. The advantage is that it can observe the rotation speed of the pump and, by conversion and projection to calculate the actual constant-rate of flow of the pump. It makes convenience in control, direct observation, adjusting more accurately the speed. It is an ideal instrument for feeding the sample (liquid) or sampling (liquid) used in your production and experiment.
Series of HL system pump with digital displaying constant-rate of flow is an instrument enable to feed or sample the liquid of fixed quality. It has the advantage of stability in conveying flow, continuous adjustment, the transported substance not exposed thus to protect the pollution, small in volume, light weighted, reliable performance. It is widely used in industrial enterprises, university and colleges,
hospital, and R&D institutions and becomes one of indispensable instruments in production and science research activities. It is even used in feeding and pumping liquid with micro-quantity and fixed quantity.
