Helical flow sensor and meter  

Helical flow meters are positive displacement meters 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 helical flow meters are an excellent choice for laminating systems, painting systems, adhesive dispense systems,  as well as batching systems for various fluids.
