一、产品简介   Product introduction

        LZZ(D)W系列是微小流量金属管浮子式流量测量仪表，可测量液体、气体或蒸汽。该仪表采用变面积式测量原理，测量部件由一个锥形测量管和浮子组成，具有坚固、稳定和应用范围广的特点。连接方式有水平连接或垂直连接，可选配入口压力变化或出口压力变化的压力调节器(恒流阀)。

        LZZ(D)W series is a small flow metal tube float type flow measuring instrument, Itcan measure liquid, gas or steam. The instrument adopts the principle ofvariable area measurement, and the measuring part is composed of a conicalmeasuring tube and a float, It has the characteristics of firmness, stabilityand wide application range. The connection mode includes horizontal connectionor vertical connection, Pressure regulator (constant flow valve) with inletpressure change or outlet pressure change is optional。

LZZW系列为现场指示型仪表，可选装一个或二个本安防爆型报警开关(需配备关联设备)；LZDW 系列为电远传型仪表，输出 4～20mA 电流信号(兼容 HART通讯协议)，指针指示瞬时流量，可选 LED 光柱现场指示流量。

LZZWseries are field indicating instruments, One or two explosion-proof alarmswitches can be selected (associated equipment is required); LZDW series areelectric remote instruments, Output 4-20mA current signal (compatible with HARTcommunication protocol), The pointer indicates the instantaneous flow, OptionalLED light column indicates the flow on site.

LZZ(D)W系列微小流量金属管浮子流量计广泛应用于石油、化工、化纤、钢铁、食品、轻工、制药等行业的微小流量测量和过程控制。

LZZ(D)Wseries micro flow metal tube rotameter is widely used in micro flow measurementand process control of petroleum, chemical industry, chemical fiber, steel,food, light industry, pharmaceutical and other industries.
