Wastewater Flow Meters

With over 45 years in the business our staff has expertise in virtually all wastewater flow meter technologies. In addition, our representation of Plasti-Fab, Inc. for over 40 years has brought us experience with all common flume types for any application.

Pressurized Lines


With just one signal converter and the widest range of flow sensors, the OPTIFLUX magmeters cover all applications, from simple water measurement to corrosive or abrasive products or even pulp and paper. Simplified engineering, procurement and inventory lead to cost-savings for the user. OPTIFLUX magmeters come standard with onboard diagnostics.


NSF Approved for potable water use

Standard Krohne magmeter for water and wastewater applications


Tidalflux from Krohne

For non full pipe applications

Measurement possible down to 10% filling of pipe

KROHNE OPTISONIC Ultrasonic Clamp-On Flow Meters >>

Unique rail mounted clamp-on design for quick and easy installations with the proven precision and reliability of KROHNE ultrasonic technology. Available in a permanent or portable version.

Isco Hot Tap ADFM Velocity Profiler >>

The ADFM Hot Tap Flow Meter provides precise and accurate flow rate measurement in pressurized pipe applications where the pipe diameter is 18". The Hot Tap’s ADFM pulse Doppler velocity profiling technology enables accurate flow rate measurement without the usual lengthy upstream and downstream straight-line conditions required by other technologies. It measures flow rate to within ±2% of actual flow rate in closed pipes, even in difficult applications such as installations near bends, short straight runs, near pumps, etc.

Magmeter Manholes >>

Now easily install a magmeter on an existing underground pipe with a magmeter manhole. Easily connects to existing pipes using neoprene boots or slip flanges. Ships with customer supplied magmeter installed.

Open Channel

Isco Signature Flow Meter >>

Available as a bubbler, ultrasonic, area velocity or a combination of these technologies (up to 9). This flow meter provides an expandable platform to allow the addition of multiple ultrasonic transducers, pH sensors, SDI-12 devices, and RS-485 devices. Data download with a USB flash drive. Available with an internal cell modem or Ethernet connection. It logs key events such as changes in calibration and power outages to validate data accuracy. Data can be easily reviewed to detect any type of data alteration.

Isco 4200 Series Flow Meters >>

4210 Ultrasonic,4220 Submerged Probe, 4230 Bubbler, and 4250 Area Velocity Flow Meter technologies all available in the same, easy to use electronics package. All models offer a built in printer for customizable reports, wide array of interfacing options, AC/DC power flexibility, rugged enclosures, and data logging. The perfect flow meter for the most common flow meter applications.

Krohne Optisound VU-31Ultrasonic Measurement System >>

Line powered ultrasonic level or flow measuring system capable of calculating flow rates in Parshall flumes with submerged flow conditions when using two ultrasonic transducers. Includes two 4-20 mA outputs and 6 SPDT relays.

2160 LaserFlow Non-Contact Flow Meter >>

Remotely measures flow in a pipe or channel using advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream. During submerged conditions, flow measurement continues without interruption with an optional Doppler Ultrasonic Area Velocity technology.

Isco 2100 Series Flow Modules >>

Isco’s modular flow monitoring system is available using the 2110 Ultrasonic Flow Module for applications utilizing a weir or flume or the 2150 Area Velocity Flow Module for pipes or channels. Stack up to 4 modules on a single AC or DC power supply for permanent or portable applications. A wide variety of communication options are available including spread spectrum radio, cell modems, landline modems, and analog outputs. Also available for hazardous area installations.

Isco ADFM Pro 20 Velocity Profiler >>

The ADFM Pro20 brings unparalleled flow measurement accuracy to large pipes and channels, delivering flow rate data within 2% of actual value, in flow depths up to 20 feet (6 m).

Four (4) piezoelectric ceramics measure velocities at multiple points in four different directions, known as bins, in the water column. This distribution of accurate velocity measurements is then used to determine the flow pattern over the entire cross-section of flow.
