This low flow flowmeter is designed for use on horizontal 1-1/2" plumbing. The flow rate may be measured between 9 and 30 gallons per minute. A dual gallons per minute and litres per minute scale is printed on both sides. Special note: For accurate flow rate measurement this should be installed in as long a run of straight pipe as possible. For this meter, 10 times the pipe diameter before and 4 times the pipe diameter after is required.
