Clark's Vortex Flow Sensors
Both the 200 and 210 Series Vortex Flow Sensors are designed specifically for OEMs for system flow monitoring and control. These sensors are excellent choices for applications like water and water/glycol-based heat exchange systems (with the usual additives) and similar fluids with flow ranges from 0.9 to 150 liters per minute (0.24 to 39.6 GPM).
Available in models for ¼-inch to 1-inch pipe sizes, 200 and 210 Series Liquid Vortex Flow Sensors feature optional temperature measurement capability and accuracy to 1% fs in liquid media up to 185°F.
Similarly, the 210 Series Vortex Flow Sensors feature a response time of 100ms and an accuracy of 1% fs of measured value. The 210 Series Sensors are equipped with increased range of power supply (4.5-33 VDC) and output signals (frequency, 0-10 V, analog 4-20 mA). With no moving parts, the flow sensor is not sensitive to debris and has marginal pressure loss and high accuracy.
