Product details

Overview
G/R/F10、 20. The connection of the 30 type glass rotor flowmeter includes pipe threads (G10, 20, 30 types) and hoses (R10, 20, 30 types); There are three types of flanges (F10, 20, 30). Its working pressure and maximum working temperature are higher than those of the original LZB/LZJ series glass rotor flowmeter products with the same diameter; There are two types: ordinary type (measuring generally non corrosive fluids) and corrosion-resistant type (measuring corrosive fluids). The product has a small volume, lightweight structure, beautiful appearance, easy maintenance, safety and reliability, and simple installation. F10、 20. The 30 type flange is rotatable and matches the flange hole of the on-site pipeline. G/R/F10、 20. The 30 type glass rotor flowmeter can replace the glass rotor instrument on imported complete sets of equipment and is widely used in chemical, light industry, pharmaceutical, food, papermaking, environmental protection, measurement testing, scientific research and other departments to measure the flow rate of single-phase non pulsating fluids (liquids or gases).

Note: 1. The pressure of the fluid entering the flowmeter must be at least twice the pressure loss of the liquid and at least five times the pressure loss of the gas.
2. Accuracy level 1.5 is required, please indicate it on the order.
3. The flow rate of the corrosion-resistant PTFE float is lower than that of the ordinary type.
4. The corrosion-resistant PTFE lining is only available in the F10 and F30 series, with models F10- () FO and F30- () FO
