What is the project?
The Enlarged Cotter Dam project involves building a new dam downstream of the existing one to increase the Cotter Reservoir’s capacity from the current 4 gigalitres (GL) to around 78 GL – almost 20 times its current size. Pumping a special formulated grout mixture, forming the damn wall itself. Using a pneumatic pump test rig, grout flow in a 25mm galvanized steel pipe, customer has been unable to measure mixture accurately, only by using a drop test.
Test Rig: - Volume in drum with agitator around 75 litres - Agitator constantly keeping slurry well mixed. - Pump: Pneumatic stroke pump – each stroke delivering about 200ml. - Strokes averaged 1-2 per second. - Pipe Material: Steel – Galvanized - Pipe ID 25.4mm - Wall thickness 2.7mm - Flow rate: 0.25 to 0.3 lps - Totalized Flow 9 L Solution: Using the Compu-Flow™ Doppler ultrasonic flow meter provided an accurate and easy-to-use non invasive Ultrasonic Flow measurement system for high-solid fluid flow through the galvanized steel.
By simply placing and securing the sensors, adjusting the settings and parameters, measurement of the grout mixture was measured within 10mins of set up.
Customer has hired the meter for a 10 day trial with the anticipation of purchasing two of the new Compu-Flow Doppler Meters.
