MT3809 系列金属管变面积流量计

温度、压力和过程范围最广泛；可靠

型号 3809G / 3809G ELF / 3809G TFE Lined / 3810G

专为需求设计：选择 MT3809 可变面积 (VA) 流量计（转子流量计），满足您下一个项目的所有高压、高温 VA 流量测量和控制要求。

事实证明，MT3809 可以在数千个安装位置提供可靠、可重复的气体和液体流量测量和控制，经济实用，从而使其成为全球工程采购承包商 (EPC) 和主要工业设施的首选。

MT3809G 的特点是为当地运营商接口配置了数字液晶显示屏，从而提供了宝贵的过程输出，如综合化和报警信号。它还允许用户更改参数，无需取下盖子，这意味着甚至可以在危险区域进行参数更改。
