国外直购TORBAR均速管流量计 wi59557

特性

●独有的内部二次平均结构，提供了高精度（读数的 ±1%）和高重复性（ ±0.1%）

●外层冲击管采用一整块材料加工制做而成，无焊接，与由双体结构焊接而成的同类产品相比，自然有*高精度，也便于选用耐高温，耐腐蚀的材质

●六边形**结构，产生了独特的流束分布形状，保证了低压信号的稳定，产生的差压高于同类产品，提高了量程比

●适用管径为10mm-8000mm或更大

●适用于方形或矩形的管道

●对任何同类产品在测量脏污介质时不可避免的堵塞问题，有在线可拔出型或提供手动和自动吹扫方案及装置，实现不停产维护

●托巴管+三阀组+温压补偿+变送器，组成一体化结构，使用更方便

●无流量系数漂移，长期稳定

●**提供直观的共振验算，确保长期稳定运行

●压损小能耗低，节能效果显著

●安装简便节省人工，价格低交货迅速（1个月）


一般规范

●适用于测量液体、气体和蒸汽的流量

●准确度为被测实际流量值的 ±1%

●测量的重复性为 ±0.1%

●流量的量程比，典型的为10：1（差压值100：1）

●*高工作温度达1300℃（用适当的材质和安装件）

●*高工作压力达400Bar（40MPa）

●*高粘度为500 cp

●要求上下游直管段的长度较短

●标准不锈钢牌号

●长期精度不受磨损的影响

脏污气体流量测量

●托巴管可用于测量脏污介质（如焦炉和高炉煤气等）的流量

●带隔离阀的多种在线式可拔出结构保证在不停产情况下清洗托巴管

●可以采用手动或自动方式用空气、氮气或蒸气定期进行在线吹扫，以**均压孔附近附着的污物，保证托巴管长期运行的准确度

托巴管已经成功地用于流量测量的一些对象有：天然气 压缩空气 饮用水 河水 海水 热气废水 CO2冷凝剂 工业煤气 烟气 低压蒸气 高压蒸气 以及其它许多许多。

COMPENSATED MASS FLOWMETER

TOTAL METER PACKAGE

The MASS TRIBAR measures pressure, temperature and Differential Pressure directly from the inserted TORBAR primary element and computes compensated mass flow within the integral multivariable transmitter.

The MASS TRIBAR is ideal for the mass flow measurement of liquids and gases. It is also suitable for measurement of saturated steam flow with the transmitter mounted vertically below the pipeline axis (see APPLICATION LIMITATION note below).

The MASS TRIBAR concept provides several direct advantages.

AVERAGED FLOW PROFILE MEASUREMENT
SIMPLE INSTALLATION
COMPACT INTEGRAL CONSTRUCTION
RTD EASILY REMOVABLE FOR MAINTAINANCE
REDUCED TRANSMISSION LAGS
LOW PRESSURE LOSS
SINGLE SOURCING
COMPETITIVE PRICING
