Ultrasonic Flow Meters
FIXED INSTALLATION WETTED SENSOR TRANSIT TIME
(Transit time is for clean water)
PENSTOCK FLOW METERS FOR HYDRO PLANTS
Risonic Modular Multi-Path Water Flow Meters for large pipes such as penstocks, tunnels and channels. Suitable for pipe diameters up to 11 meters (36-feet) and open channels 7 to 70 meters wide, these meters achieve accuracies to +/- 0.5% of rate. The Risonic Modular flow meters meet the standards of the IEC-41 and ASME PTC-18 codes for hydro-electric turbine efficiency testing.
In 2015 Cascadia supplied a Rittmeyer Risonic Modular eight path, turbine efficiency testing transit time flow meter to Jimmie Creek Hydro Project in the Upper Toba Valley, BC. Cascadia has supplied Risonic flow meters to more than 15 hydro projects since 2000.

FIXED CLAMP-ON TRANSIT TIME
Risonic Modular Clamp-ON – Non-intrusive flow measurement (no drilling, no interruption of operation) Magnetic frame eliminates mounting straps and also works on partly exposed pipes. Durable and long-term solution, option for adhesive mounting of magnetic frame. Measuring accuracy of up to 1.5% of measured flow. Flow measurement in both directions (pumped-storage power plant). Advanced mathematical calculations (total flow, average of delta flow, etc.) Web server for easy configuration and remote diagnosis. IEC 60870-5-104 and Modbus RTU/TCP communication. Mobile metering with possibility for battery-powered operation.
PORTABLE-HAND HELD- CLAMP-ON TRANSIT TIME
The HHT-05 Hand Held clamp-on Ultrasonic Transit Time flowmeter is Ideal for monitoring full pipe clean liquid applications. Suitable for metal and plastic pipes. Magnetic transducers install easily on ferrous metal pipes and it includes a strap on mounting kit for non-ferrous and plastic pipes. Typical applications are; river water, well water, chilled water, hot water, potable water, cooling tower water, de-ionized water, sea water and acids.

FIXED CLAMP-ON DOPPLER (F-100-DFM5)
The F-100-DFM5 installs easily on metal and plastic pipes that are full of liquid. This flow meter is recommended for dirty liquids including wastewater, sewage, sludge, paper stock, slurries and more. Application requirements are for liquids with suspended solids or aeration greater than 100 microns (75ppm).

PORTABLE CLAMP-ON ULTRASONIC DOPPLER
Ultrasonic Doppler flow meters are for; dirty or aerated liquids, some slurries and lubrication fluids, in full pipes.
Use it to monitor and balance flow, or to troubleshoot flow problems in full pipes. It is ideal to evaluate performance of in-line flow meters and can be installed, calibrated and started-up in minutes. Use it for projects where a permanent flow meter is not required or to temporarily replace installed flow transmitters.
