原理:

流体流经开关的旋转磁场,转子诱导线圈的电压。一个简单的电子电路比较测量电压用户当选行程电压,

在一定时间内测得的电压是上述选定的触发电压继电器是主动的地位举行。测得的电压低于选定的触发电压

或当流体停止流动时,继电器被关闭。继电器触点的状态的变化,是用来触发您的联锁或报警系统。

标准500系列计量流量开关校准与水约25°C / 77°F。使用其他液体比水的差异可能会影响测量的准确性粘度。普罗透斯的世界级的校准能力使我们有专门提供仪器温度,fluid-specific校准。

Section 1 Introduction

500 Series Metering Flow Switches have been created to provide a more effective monitoring and control

capability for applications in which liquid flow rates up to 4.5 GPM (17 LPM) must be monitored and

controlled over extended temperature and pressure ranges.

Capabilities required for extreme operating conditions have been incorporated in the basic product,

allowing the size-reduced metering flow switch to be used in situations in which specialized products were

previously required.

The 500 Series Metering Flow Switches have been developed from Proteus’ experience in satisfying the

needs of thousands of demanding users in widely diverse applications since 1978. 

Note

The flow response of 500 Series sensors and thus their calibration may be dependent on the form of the

device attached to the inlet connection and other closely located up-stream devices.

Elbows, T-pieces, valves and filters located immediately up-stream from the flow sensor can introduce

swirling motion to the liquid flow. The swirling motion reduces the linear velocity of the flow stream.

We recommend that a straight run of pipe of more than 10 x pipe ID (~4 inches or 10 cm) be used

between the flow sensor and any up-stream devices to minimize these effects.

Appropriate calibration procedures must be used to provide an accurate flow measurement with elbows

or T-pieces that must be attached directly to the inlet connection.

The 500 Series sensor is typically unaffected by the form or proximity of devices on its downstream side
