厂家直销高温型流量计 高温型涡轮流量传感器 耐温180℃

LWGY型涡轮流量计为一种速度式流量计量仪表。用于测量充满封闭管道，连续流动的液体体积流量。LWGY型涡轮流量计与相应的流量显示仪表——XSJ系列流量积算仪配套使用，也可与LWGY/TBS型转换显示器等组合在一起构成一体型，用来测量并显示液体的瞬时流量和累积流量，且可输出电压及电流脉冲信号和/或标准电流信号，还具有失电数据保护功能和自诊断功能。

This instruction manual describes the standard specifications, model,installation,operation and maintenance of the turbine flow meter.Type LWGY turbine flow meter is a velocity flow meter.It is used to measure volume flow rate of a liquid that fills a closed pipeline and flows continuously in it.In actual application, Type LWGY turbine flow meter integrates with relevant flow indication instrument-XSJ Series flow integrating instrument, also, it may combine with LWGY /TBS converter display to form a integral type to measure and indicate flow raterate and quantity of a liquid, to pulse output signals and/or standard current signals and to provide power-off data protection.

涡轮流量计适合于测量粘度低的液体，具有精度高、可承受的工作压力大、介质的温度范围宽等特点。广泛用于石油化工、冶金、科研等领域，也可用于食品行业和液压系统上。前置放大器按输出信号型式分为：电压脉冲型、4~20mA标准电流信号输出型。按防爆型式分为普通型（非防爆）、隔爆型、本安型。流量检测器有普通型、耐磨型和防腐蚀型，其中耐磨型除轴承和轴采用硬质合金（25mm口径以下轴承采用红刚玉）外，并设计成对叶轮有适当的反推力，使之更适合于测量汽油等润滑性能较差的液体。防腐蚀型在压力不超过1MPa,介质温度为常温下，可采用全塑结构。

The turbine flow meter is suitable for measuring a liquid flow rate of low viscosity, featuring a high accuracy and a strong bearing capacity of high process pressure.The product may be widely applied in petrochemical industry, metallurgical industry and other fields of scientific research. It may also be applied in food service industry and hydraulic systems. The pre-amplifiers are classified into common type, 4~20mA standard current signal output type and explosion proof type, and the flow detectors fall into common type, wearing resistant type and anti-corrosive type, among them, for the wearing resistant type, aside from its bearing and shaft made of hard metal (for a diameter lower than 25mm, red corundum will be used.), it has been designed to a pattern providing a proper reverse thrust to the impeller, which has made it more suitable for measuring liquids of poor lubrication.performance, such as gasoline etc.
