Town operators were plagued by high level alarm call outs at two new sewage lift stations. Read how they used Greyline's hybrid ultrasonic level controllers with dual sensor capability to put an end to level alarms.
Greyline AVFM Area-Velocity Flow Meters monitor and totalize irrigation water distributed through a network of canals, channels and pipelines in the United Irrigation District.
Wax and solids build-up were plugging off pipes and in-line flowmeters at this oil battery site in Alberta. Read how Petrobakken Energy solved the problem by switching to Greyline DFM 5.0 Doppler Flow Meters with non-contacting ultrasonic sensors.
A new TTFM 1.0 Transit Time Flowmeter monitors and logs irrigation water pumped to sprinklers at Summerheights Golf Links. The clamp-on flowmeter is used to comply with a Ministry of Environment permit.
Since 2007 Thurston County has deployed Greyline Area-Velocity Flow Meters in open channels resulting in thousands of dollars in savings every year.
The world's largest single producer of copper was faced with a challenge in their heap leaching process in the Atacama Desert of northern Chile. Finding an accurate, reliable non-contacting flow meter was a difficult task.
From sewage pump stations in the collection system, through final treated effluent, the Township of Edwardsburgh/Cardinal deploys Greyline flow and level instruments.
Dredge operators need accurate real-time flow information to properly manage production. But dredging slurries are very abrasive and pumped at high velocity so flow measurement is difficult. Manufacturers find the solution with Greyline clamp-on flowmeters.
Level monitoring and control is a fundamental requirement in any wastewater treatment process. You will find level instrumentation installed at even the simplest treatment plants for pump control, chemical storage tanks and process level controls or alarms. Operators have only limited or emergency control over treatment plant influent, so level controls and instrumentation play an important role in managing the wastewater treatment process.
Limestone Slurry is abrasive therefore in-line flowmeters are not practical. Non-contacting Doppler Flowmeters can be used both on the fly ash slurry supply lines and on "used" or recirculated slurry.
Greyline DFM 5.0 Doppler Flow Meters with waterproof ultrasonic sensors measure flow in submerged concrete culverts in the Raymond Irrigation District in Alberta, Canada.
Greyline AVFM Area-Velocity Flow Meters are installed thoughout the country by Teletronic Denmark to monitor municipal sewage and stormwater. Application photos and descriptions illustrate flow monitoring in manholes and open channels.
A Greyline AVFM Area-Velocity Flow Meter monitors and data logs water discharged from the Bray Quarry to the South Raisin River. The Quarry is required to measure flow for environmental permit compliance.
The septage receiving station in Whynott's Settlement, Nova Scotia needed a simple, compact solution to control VFD-driven vertical turbine pumps, chlorine injection plus flow through a V-Notch Weir with display and 4-20mA outputs... Solution: the Greyline DLT 2.0 Differential Level Transmitter
An Ontario municipality deploys Greyline portable flowmeters to solve flow rate discrepancies between a magmeter installed on the forcemain in their pump station and an open channel flowmeter at the sewage lagoon.
After 16 years of service, the Long Sault WWTP replaced two older Greyline Open Channel Flow Monitors with new data logging OCF 5.0 models. This SBR treatment plant's influent is measured with flow through two 6" Parshall Flumes.
Culligan Water installs Greyline SLT32 Level Monitors to control tank levels in their bottling plant in Calgary, Alberta. With non-contacting ultrasonic sensors the SLT32's control fill and discharge valves in five tanks containing spring water, reverse osmosis water and distilled water.
The Glen Walter Sewage Collection System was built to service 1,080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Plant operators and the municipality had concerns about the excess flow
CanFrac Sands Ltd. of Lloydmister, Saskatchewan install a Greyline DFM 5.0 Doppler Flow Meter to measure fracturing sand slurry when their in-line flowmeters were being damaged by the abrasive slurry.
The Township of South Glengarry installs a new Greyline AVFM 5.0 Area-Velocity Flow Meter to measure continuous discharge from their municipal sewage lagoon. The sealed ultrasonic sensor is mounted in a horizontal 12" PVC pipe. The AVFM replaced a magnetic flowmeter that was unable to measure seasonal low flow rates.
