Determining Flow Rate at Various Points on a Golf Course

A groundskeeper at a large golf course needs to measure the flow rate in the watering system at more than 30 different points throughout the course. With several miles of pipe, the diameters vary from 2 to 4 inches. The groundskeeper also indicated they want to monitor the flow continuously for 10 minutes at each point of measurement. They have a budget of less than $10,000. Which flowmeter and process would be ideal for this application?

A: Install spring-loaded flowmeters at each point around the course. Take readings every 15 seconds and record them in a notebook.

B:  Install tee-fittings with paddle wheel sensors at each monitor point, and carry a battery powered meter around the course. Take readings every 15 seconds and record in a notebook. 

C:  Use a Handheld Doppler Flowmeter and take readings every 15 seconds and record them in a notebook.

D:  Use a Portable Transit-Time Flowmeter and program the datalogger’s sample rate for one reading per second.

Check to see if you are right.
