Jan 12, 2011 Designed for municipal stormwater, combined effluent, raw sewage, and irrigation water, AVFM 5.0 can monitor flow through open channels, partially full sewer pipes, and surcharged pipes without flume or weir. It can be configured with standard submerged velocity/level sensor, or with submerged velocity and separate non-contacting ultrasonic level sensor. Additional features include backlit flow rate display, totalizer, three 4-20 mA outputs, and 2 control relays.

Differential Level Controller also measures flow.

Greyline Instruments, Inc.    Massena, NY 13662
Sep 17, 2010 Intended for use in treatment plant headworks, DLT 2.0 can measure differential level at barscreen as well as open channel flow through flume. It works with 2 non-contacting ultrasonic sensors: one installed upstream from barscreen, and another installed downstream for differential level control. It is also possible to install second sensor in flume to also measure flow. Along with backlit LCD, features include relays for barscreen rake and level control as well as three 4-20 mA outputs.

Portable Ultrasonic Flow Meter works from outside of pipe.

Dec 28, 2009 Designed for measuring clean liquids like water, oils, and most chemicals, Portaflow PT500 Transit Time Flow Meter works with any plastic or metal pipes from 0.51-78 in. OD, and can be used for troubleshooting, spot checks, and balancing flow. It features backlit graphics display, 4-20 mA output, data logger, RS232 and USB outputs, and OS with quick start calibration menu. Operating 16 hr on internal battery, unit can store calibrations for up to 20 different sites.

Portable Doppler Flow Meter has 320,000 point data logger.

Greyline Instruments, Inc.    Massena, NY 13662
Dec 28, 2009 Mounting to outside of plastic/metal pipes, compact, hand-held flowmeter PDFM 5.0 displays flow rate, and can also totalize and data log in choice of gallons, liters, or any engineering units. Features include 4-20 mA output, large backlit display, reverse flow measurement, menu language selection, USB output and Windows(TM) software, and rechargeable NiMH battery. Unit is suited for use with wastewater, sludge, slurries, chemicals, and abrasives.

Tank Monitoring System manages up to 32 tanks.

Greyline Instruments, Inc.    Massena, NY 13662
Sep 01, 2009 Tank Farm Level System leverages Windows(TM) TFS Tank Farm Supervisor software, which lets operators supervise tank fills/discharges and monitor tank farm inventory from one central location. Able to concurrently monitor up to 32 tanks, system can also automate daily or work shift inventory logging; individual tank levels data will be logged at programmable intervals on PC's disk drive. Also, tank levels and control relay status are continuously displayed at each tank and monitoring PC.
