FLOW & PRESSURE DROP
Maximum flow ranges to 8 GPM/32 LPM = pressure drop from 1.9 to 2.5 PSID (2.2 PSID average).
Maximum flow ranges to 9 to 12 GPM/45 LPM = pressure drop from 1.9 to 4 PSID (2.95 PSID average).
Maximum flow ranges to 15 GPM/56 LPM = pressure drop from 1.9 to 5 PSID (3.5 PSID average).
Maximum flow ranges to 16 GPM/60 LPM = pressure drop from 1.9 to 5.5 PSID (3.7 PSID average).
Maximum flow ranges to 20 GPM/75 LPM = pressure drop from 1.9 to 6 PSID (4.0 PSID average).
INSTALLATION
Flow monitors mount in-line and are typically supported by rigid pipe.

UFM流量开关SN/SM/SH系列介绍

These are variable area meters with a spring biased semi-circular vane that opens wider with more flow. They are installed in-line in any position. Straight pipe runs before or after the meter are not required. The simple mechanical connection directly drives pointers, switches and transmitters.

READOUTS

The flowmeter has outputs both visual and electronic. Visual displays are either pointer (with inscribed scale) or numeric (digital LCD). Electronic outputs can be mechanical switch closure, 4-20 mA analog or both (for signal redundancy). The switches can be general purpose or rated for hazardous locations (all classes, groups and divisions). The 4-20 mA transmitters are Intrinsically Safe if used with approved barriers.

CALIBRATION

All flow meters are individually calibrated for fluids with the viscosity you specify (up to 3000 SSU/650 Centistokes). We also compensate for your fluid's specific gravity. For NIST Traceability please consult factory.

CONSTRUCTION MATERIALS

The meter body, internal moving parts, and seals are offered in a variety of materials to suit a wide range of applications: water, synthetic and petroleum based oils, paint, corrosives and solvents. See selections in the “How to Order” section.

LINE CONNECT

Ports can be threaded or flanged. See selections in the “How to Order” section.

这些是可变面积流量计，带有弹簧偏置的半圆形叶片，打开更大，流量更大。它们在线安装在任何位置。不需要在仪表之前或之后运行直管。简单的机械连接直接驱动指针、开关和发射器。

读数

流量计具有视觉和电子输出。视觉显示是指针（带有刻度）或数字（数字 LCD）。电子输出可以是机械开关闭合、4-20 mA 模拟或两者兼有（用于信号冗余）。这些开关可以是通用的，也可以用于危险场所（所有类别、组和分区）。 4-20 mA 变送器如果与经批准的安全栅一起使用，则是本质安全的。

校准

所有流量计都针对具有您指定粘度（高达 3000 SSU/650 厘沲）的流体进行单独校准。我们还补偿您的流体比重。有关 NIST 可追溯性，请咨询工厂。

建筑材料

仪表主体、内部运动部件和密封件采用多种材料制成，以适应广泛的应用：水、合成油和石油基油、油漆、腐蚀剂和溶剂。请参阅“如何订购”部分中的选项。

线路连接

端口可以是螺纹或法兰的。请参阅“如何订购”部分中的选项。
