Dwyer Series FMS Flow Sensor

Flow Sensor
Series FMS

Series FMS Flow Sensor FMS-1 is for applications requiring RELATIVE measurement and set-point of flow rate. This means that the actual velocity of the flow or the quantitative measurement in GPM is not known and is not important. What is important is that the set-point can be set as a “percentage of” or “relative to” the full flow rate. No other flow sensor could do it this simply or effectively.

• Automatic scaling and set-point
• No moving parts
• Learn function for flow rate
• Push-button re-scaling if needed
• Easy to install
