LLQ series gas Roots flowmeter

The main technical performance indicators comply with the requirements of JB/T 7385 and JJG 633 standards;
Nominal diameter: DN20 to DN100;

Wide range ratio (1:160), high measurement accuracy, low starting flow rate, and small pressure loss.

The specifications and basic parameters of the flowmeter are as follows:
