Pump Station Level Control for the Town of
Two new sewage lift stations were plagued by callout alarms from ultrasonic level
controllers as foam and grease covered the water surface and caused
echo loss. Operators installed new Greyline PSL 5.0 Pump Station
Level Controllers with redundant sensors to permanently solve the
Differential Level Transmitter in the ville
de Port-Cartier WWTP
When the Town of Port-Cartier needed to
automate operation of the barscreen rake in their Wastewater
Treatment Plant they selected the DLT 2.0 Differential Level
Transmitter from Greyline Instruments. Here's how it works.

The new PSL 5.0 Pump Station Level
Controller and PTFM 1.0 Portable Transit Time Flow Meter are
introduced at WEFTEC 2012 in New Orleans.
Ultrasonic Flow Meter Transducer Installation
Watch us install transducers for a Greyline TTFM 1.0 Ultrasonic Transit Time
Flowmeter. We demonstrate sensor installation on a PVC pipe with
mounting brackets and clamps supplied with the instrument.
Start-up of a PDFM 5.0 Portable Doppler Flow
It's easy to mount the clamp-on ultrasonic
sensor and start-up the PDFM 5.0 to measure flow in pipes 1/2" diameter or
Temporary Sensor mounting for spotchecks
can use electrical tape to mount the PDFM 5.0
Portable Doppler Flow Meter sensor on the outside of pipe 1/2"
diameter or larger. You can use electrical tape to secure the sensor
on the outside of metal or plastic pipes. It takes about one minute.
Install a 2 million point Data Logger in an existing Greyline instrument
It's easy to add a data logger to Greyline flow
or level instruments that are already in service.
New 5.0 models auto-detect hardware
changes so you simply plug-in the logger circuit board. When the
instrument powers up, data logger settings automatically appear in
the calibration menu. Greyline data loggers also download directly
to USB flash drives - so you don't need to carry a laptop to the
instrument to retrieve logger files.
Greyline Pipe Band Sensor
Mounting for Area-Velocity Flowmeters
Do it the easy way - use a stainless steel pipe
band for Area-Velocity Flow Meter sensor mounting. You can install
the sensor and tie wrap the cable in place before you enter the
manhole. Then insert the pipe band into the manhole inlet pipe and
tighten the scissor-jack to expand the band for a friction fit
inside the pipe.
Watch installation and calibration of a
Portable PT500 Transit Time Flow Meter from Greyline Instruments. A
pair of ultrasonic transducers are mounted on the outside of a pipe.
Use the PT500 to measure flow of clean fluids in pipe diameters from
13 to 2000 mm (0.51" to 78"). The flow meter is installed without
cutting pipe or shutting down flow.
Add Relays to a Greyline Flow or Level
It's easy to add relays to a Greyline
instrument. Power the unit off, plug in the relay board and power
back on. The instrument detects the new hardware and automatically
loads the menu system for calibration. In this video we add four
relays to a Greyline DFM 5.0 Doppler Flow Meter. Following the same
procedure you can also add a data logger. It takes just a couple of
minutes for complete installation.
Datalogger USB Download
Greyline flow and level instruments with USB
flash output can download directly to external thumb drives. Simply
plug in a thumb stick and the data download begins automatically.
When the instrument displays "Completed" the thumb drive can be
disconnected. Run Greyline Logger software on your Windows PC to
open the logger file.
