羅茨流量計又名氣體腰輪流量計是一種高精度、高可靠、寬范圍度、低始動流量的容積式氣體計量儀表,可直接測量氣體的工況體積流量和總量,也可通過配置體積修正儀,測量氣體的溫度、壓力、標況體積流量和總量,可選配DTU模塊,實現無線遠傳。已大量應用于城市燃氣和工業氣體流量計量與檢測,是用戶實現高精度、高可靠計量的理想儀表。
Roots flowmeter, also known as gas waist wheel flowmeter, is a volumetric gas metering instrument with high accuracy, high reliability, wide range, and low starting flow. It can directly measure the operating volume flow and total amount of gas, or measure the temperature, pressure, standard volume flow, and total amount of gas by configuring a volume correction instrument. DTU modules can be optional to achieve wireless remote transmission. It has been widely used in urban gas and industrial gas flow measurement and detection, and is an ideal instrument for users to achieve high-precision and highly reliable measurement
