Overview
The Eno Scientific WS 131 features a simple design consisting of a PVC housing and an electronic sensor module that easily attaches to the housing using a hand-tightened ring nut. Once the sensor is installed, it transmits electrical pulses that are generated as water moves past the paddle wheel. The amount of water volume that passes through the pipe can be interpreted by an Eno Scientific water level meter like the Well Sounder 2010 Pro. During inactivity, the sensor can be removed and replaced with an inexpensive plug with the same kind of hand-tightened ring nut concept.
Design
Flow meter housings are available in various sizes. The 1", 1.5" and 2" housings are in-line tees made with Type 1 PVC with sockets for schedule 40 PVC pipes, and compatible with common PVC piping and adhesives. The 3" and 4" housings are saddle tees made of Type 1 PVC which clamps onto schedule 40 PCV pipes. The paddle wheel is made of a tough polyethylene material and is the only object subject to wear in the entire system. In the case of highly abrasive water flow, the paddle wheel may experience wear with time but is easily replaced without tools.
Mechanics
The electronic flow sensor operates off a 5-24 VDC power supply and provides an output voltage on the signal line, which switches between Vin and ground as the paddle wheel turns. Data collection is configurable by either plugging a ready-to-plug cable into the Well Sounder 2010 Pro, or with three-wire leads for connection to other data logging devices. An accessory splitter is necessary for the Well Sounder to monitor and log data from both the flow meter and the probe.

Angler-Driven Citizen Science: Monitoring Black Bass Populations in Arkansas
In Arkansas, the rugged terrain of the Ozark and Ouachita Mountains dominates the north and west, eventually yielding to the vast, fertile flatlands of the Mississippi River Delta to the east. Hundreds of reservoirs and lakes punctuate the landscape, while swift streams snake through the valleys and hills, eventually giving way to the slow-moving rivers and bayous in the south. The waterways of the state are teeming with life. Black bass dominate most of these ecosystems and have drawn anglers for centuries. The most sought-after fish in one of the country's most prominent fishing states, Arkansas treasures its black bass populations.

New Buoy Boosts White Lake’s Water Quality Monitoring and Conservation
White Lake in Western Michigan is a vestige of North America’s glacial past, and gets its name from an interpretation of the Indian, “Wabish-Sippe,” meaning the river with white clay. The twin towns of Whitehall and Montague, which nestle on White Lake’s shore, have shared a close connection with the lake since their foundation–from the growth of the lumbering industry, to industrializsation, the expansion of tourism, and most recently, environmental protection. The White Lake Association (WLA) was founded in 1988 by residents concerned about proposed development at the lake’s northern end.

Flow Photo Explorer: Studying Flows in the Penobscot River Basin
The flow dynamics of rivers and streams play an essential role in the chemical and physical functions of aquatic ecosystems. In Maine, varying flows in the Penobscot River Basin have impacted the health of the ecosystem, water resource use, and habitat suitability for native species—topics of particular concern to the Penobscot Indian Nation , who have been protecting and managing the waterway for millennia. Parts of the Penobscot basin have been monitored by the USGS stream gage network, which covers larger streams and rivers but excludes many of the small streams found on tribal lands.
