How Thermal Flowmeters Work

Dwyer Instruments — Wed, 25 Oct 2023 18:32:03 +0000

Thermal flowmeters use the thermal properties of the fluid to measure the flow of a fluid flowing in a pipe or duct. In a typical thermal flowmeter, a measured amount of heat is applied to the heater of the sensor. Some of this heat is lost to the flowing fluid. As flow increases, more heat …

How Ultrasonic Flowmeters Work

Dwyer Instruments — Wed, 23 Aug 2023 17:27:56 +0000

Ultrasonic flowmeters use sound waves to determine the velocity of a fluid flowing in a pipe. At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections from the fluid are the same. Under flowing conditions, the frequency of the reflected wave is different due to the Doppler effect. …

Pump Controller with Level Transmitter Control Pumps in Wastewater Lift Stations

Dwyer Instruments — Wed, 31 May 2023 20:52:41 +0000

Lift stations are used to transmit wastewater to a treatment facility. In residential areas, lift stations may be located in a central point to a subdivision or community. Lift stations are pits located at points in the wastewater system to collect the wastewater and usually have two submersible pumps. In order to use gravity to …

What is Wastewater, and How is it Treated?

Dwyer Instruments — Thu, 20 Jan 2022 02:05:58 +0000

Every day, billions of gallons of wastewater are collected from our homes, businesses, and industries. Wastewater is exactly what it sounds like: water that has already been used and disposed of via a tub, toilet, sink, or storm drains. Because it is full of contaminants that make the water no longer suitable for use, it …

Capacitive Level Monitoring in Wastewater Treatment Facilities

Dwyer Instruments — Wed, 20 Oct 2021 19:44:24 +0000

From dairy to petrochemicals, several applications require monitoring or control of liquids in tanks. Wastewater facilities are among the many industries requiring meticulous observation. The technology used for this measurement is dependent upon the type of tank and its contents. Capacitive level switches, for example, detect level and send a switch signal output when the …
