SRZ-H High Resolution Helical Positive Displacement Flow Meter

The SRZ Helical Gear Flow Meter is a high-resolution, strong, and affordable positive displacement flow meter offering wide measuring ranges and low pressure drop. It is ideal for highly filled and abrasive fluids, such as polyurethanes and polymers, glues and sealing materials, as well as heavy fuel oils. These positive displacement flow meters are equipped with a built in sensor and are capable of maintaining consistent accuracy of ±0.5% despite changing viscosity conditions.
