Plastic Flow Sensors, FlowStat ES Plastic Flow Sensor, Lake MonitorsA Flow Sensor That’s Compatible...With Your Application And Your Budget.

FlowStat ES Plastic Flow Sensorce

Plastic Flow Sensors, FlowStat ES Plastic Flow Sensor, Lake MonitorsWhether 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.
