HS-LGHX 环形孔板流量计是我公司在标准孔板的基础上研发的节流式流量传感器，由于它采用环形通道式结构，使测量的各种脏污介质在通过孔板与管道之间的环缝时可以轻松通过。因此环形孔板流量计广泛应用于脏污介质的流量测量。
二、特点
1、 测量含有固体微粒的液体或气体；
2、 无需长直管段，可在恶劣的管道条件下工作；
3、 适用于饱和蒸汽、压缩空气、煤气、燃炉废气、冷却水、冷凝液、和各种腐蚀性化工溶液以及各种流体介质的测量；
4、 压力损失小，功耗低；
5、 在恶劣条件下流出系数稳定，精度高，可靠性好；
三、主要技术参数
1、 公称通径：DN50~DN3000
2、 工作温度：-200~450℃
3、 公称压力：-0.1~40MPa
4、 精度：1.0% 1.5% 2.0%
5、 连接方式：法兰连接 焊接连接
