In some water level sensing applications whether they are tank level, river and lake height or similar, it is sometimes necessary to use an alternate mounting method especially when an unobstructed path to the target is not feasible or there is a lot of foam or turbulence which can disrupt water level readings. This is necessary, especially with ultrasonic technology.
One such choice of alternate mounting is the use of a stilling well, as seen above with an MNU Ultrasonic Level Sensor, mounted under a manhole cover in a sewer application.
APG's PT-L1 Pressure Transmitter measures the inlet and outlet water pressures of the PRV. The PT-L1’s 4/20mA output signal is sent to a control system whereby city personnel can monitor the water pressures with a Smartphone, thus, helping prevent any possible water mishaps that could come from over pressured waterlines.
The Water and Wastewater industry provides many opportunities for liquid level measurement. (It helps that there is so much water to keep track of.) Opportunities can turn into challenges, though, if the measurement technology chosen can’t meet the demands of the job. No matter what the demands may be, APG’s new Series PRL True Echo™ Pulse Radar Level Transmitter For Liquids is up to the challenge.
Lift stations are an essential component to municipal water and wastewater systems. Without them, many urban centers throughout the world would simply not exist. So keeping them in operation and performing properly is absolutely vital.
Lift stations that aren’t performing properly could spell disaster, especially if an overflow occurs. In addition to the unsanitary conditions and property damage an overflow creates, there is a hefty fine imposed by the EPA (think tens of thousands of dollars per day). Therefore, monitoring the water level in the station is critical. Level sensors can be used to trip alarms or turn on/off pumps automatically if an alarm condition exists.
There are a variety of instruments available to use for lift station level monitoring...

Ever wondered how to mount an ultrasonic in the open air, above a body of liquid in a stream or pond?
The truth is you can mount an ultrasonic sensor above open water however you want – as long as it follows the basic rules of ultrasonic mounting. Here are the rules again...
