Tianjin Sure Instrument Science & Technology Co., Ltd.
LLQ rotary meters are suitable for handling most types of clean, common gases at either constant or varying flow rates, and also pressure. They are ideal for applications throughout the meter’s operating range, from a few ounces to full maximum allowable operating pressure.
1. Operating Principle
The gas rotary meter is designed to measure the volume of gases and gas mixtures with high accuracy. This flow meter is in conformity with National Standard JB/T 7385-94 <Gas Rotary Meter> and enterprise standard Q/ZCY 05-2002 <LLQ TYPE Rotary Meter>
2. Product Advantage
l Proven High Accuracy, measurement accuracy is not affected by changes in gas specific gravity, pressure, or fluctuating flow.
l No straight pipe required, suitable to be installed at narrow place
l Low starting rate, wide turndown ratio, suitable for widely fluctuating flow measurement
l Local display for flow rate with multiple signal outputs
