LS-4B water meter test bench is a traditional test bench for over twenty years. It is used to test water meter DN15-DN50. Now adopt advanced technology in welding and polish treatment, 304 stainless steel and controlled by two-position four- way valve, flow rate adjusted by stainless steel ball valve, it can ensure the high accuracy, durability and nice appearance. With new function to take out and install the water meter, it is convenient in operation and easy for maintenance. LS-4B water meter test bench an ideal test bench used in water meter factories, water companies as well as measuring dept. It is in accordance with latest international standard ISO4064-4.
STRUCTURE AND PRINCIPLE
The basic water meter test bench is composed of the bench , clamp fixture, back and front straight pipe, flow meter group, standard measuring instrument and the outlet valve.
When the inlet is connected with the stable water source, the water will enter into the standard measuring instrument through the straight pipe. Compare the value of the checked water meter with that of the standard measuring instrument to get the reading error of water meter under test.
