This helical meter w/ built-in sensor is capable of 3 times the resolution of our SRZ-BB, making it ideal for small volume dosing of highly abrasive fluids.
The SRZ-H High Resolution Helical PD Flow Meters are ideal for high viscosity non-lubricating and abrasive fluids with suspended particulates, such as water-based paints, 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.
