Vision Turbine Flow Meters


Vision Series turbine flow meters comply with lead-free provisions of the United States Safe Drinking Water Act (SDWA) and are bisphenol A (BPA) free. The compact meters are designed for flow measurement of low-viscosity and non-aggressive liquids, including de-mineralized water, alkaline solutions, oils, fuel, beverages, water solutions, and coolants.


The Vision turbine flow meter is intended for use in diverse applications found in the food, medical products, chemical, pharmaceutical, automotive, and general industrial fields. The Vision Series consists of two turbine flow meter models: the BV1000 for measuring liquid flow as low as 0.026 GPM and up to 0.65 GPM, and the BV2000 for measuring liquid flow as low as 0.13 gpm and up to 9.2 GPM. The flow meters provide accuracy of ±3% with resolution up to 70,000 pulses per gallon (ppg), depending on the model.


They have a temperature range of –4 to 212°F and withstand operating pressure up to 362.50 psi. The Vision turbine flow meter employs a volumetric operating principle, whereby liquid flow causes a bladed turbine inside the meter housing to turn at an angular velocity directly proportional to the velocity of the liquid measured. As the blades pass beneath a magnetic pickup coil, a frequency signal is generated. Each pulse is equivalent to a discrete volume of liquid. The frequency pulse is directly proportional to the turbine angular velocity and the flow rate. The large number of pulses generated by the Vision meter ensures high resolution. The pulses can be used for digital or analog signal processing and specified as a K Factor. As the mass of the turbine is small, the response time is fast. It is not necessary to install a straight length of pipeline upstream of the meter.
