A Flow Sensor That’s Compatible...
With Your Application And Your Budget.
 
 Whether it’s a unique flow monitoring application, a limited budget or both, the FlowStat ES is a perfect fit. A new addition to Lake’s line of popular FlowStat® Sensors, the ES version features a durable polypropylene body for cost savings and compatibility with a variety of fluids. The ES sensor also offers a flow measuring accuracy of ±2% of full scale, and is capable of handing pressures up to 150 PSIG and temperatures up to 150°F. For additional compatibility, the FlowStat ES Sensor offers 4-20 mA, 0-5 VDC, pulse or relay outputs. And like most of its products, Lake Monitors backs the FlowStat ES/Economy Flow Sensor with a 5-year warranty.
