Description
Helical rotor positive displacement flow sensor and meter specially for replace oval gear flow sensor at some application where liquid is not pure and require easy and low weight flowmeter with a very favorable low pressure drop behavior therefore perfectly suited for the flow measurement of very high viscosity fluids. Due to wide measuring ranges, high accuracy and resolution.
Advantages
Wide range of design options for different media, economical or high specification options to suit all budgets.
Performance Data
Flow rates: 3~15000 l/min , pressure up to 400 bar,independent of viscosity, perfect for 1~1000 mm²/s,low pressure drop, high resolution, pulsation-free measurement, non-sensitive to pulsating flows, resistant to corrosion by advanced materials.
Application
Light and heavy fuel oils, thixotropical fluids, hydraulics test rigs with varying viscosities and fluids, crude oil, furnace oil, and all viscous liquid even viscosity change with temperature. Excellent choice for laminating systems, painting systems, adhesive dispense systems, as well as batching systems for various fluids.
