The AW-Lake FlowStat sensors are available with either a stainless steel or polypropylene body, depending on your flow monitoring needs. Both units feature an accuracy of ±2% of full-scale and a repeatability of ±0.5% of full-scale. For additional compatibility, the AW-Lake FlowStat sensors offer 4-20 mA, 0-5 VDC, pulse or relay outputs.

Port Sizes for the AW-Lake FlowStat Sensors

The 1/2" port size features a 0.5-15 GPM (2-60 LPM) flow measuring range.
The 3/4" port size has a 1.5-50 GPM (60-200 LPM) range.
The 1" port size has a 1.5-50 GPM (60-200 LPM) range.

Regardless of port size, the AW-Lake FlowStat sensors with stainless steel bodies have a 10:1 turn down ratio and temperature range of 20-225°F (-7 to 107°C).

The ES version of the AW-Lake FlowStat sensors feature a durable polypropylene body for cost savings and compatibility with a variety of fluids. The ES sensor still 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.

This product can be used in the following applications:

Here's how some of our customers use this product...

Low-Cost, High Pressure Pulse Meter

The Background: Our customer manufactures a range of multi-stage pumps designed for dewatering mines. They require a simple pulse meter to be used in a pump prototype they are currently developing

The Problem: Striking a balance between cost and performance will be critical. Even though the pump is capable of producing pressures up to 450psi, since it is only a prototype, the customer wants to keep the cost as low as possible.

The Solution: We recommended a Lake Monitors FlowStat flow sensor. With an all stainless steel body and cover options selected, the FlowStat provides a pulse output for simple water flows up to 500 PSIG.
