LOW FLOW ULTRASONIC FLOW METERS / CONTROLLERS - ES-FLOW™ series

ES-FLOW 低流量超音波流量計/控制器

小體積流量測量，與流體特性無關

ES-FLOW 是用於極低流量範圍的體積液體流量計。這些儀器採用創新的測量原理，在非常小的直管中使用超音波。可以測量範圍廣泛的液體，而不受流體密度、溫度和粘度的影響。

流速從 0.4 ml/min 到大約 1500 ml/min，取決於例如可用壓降。

Video ES-FLOW Ultrasonic Flow Meter

In this video clip, we proudly present the principle of operation of our new ultrasonic flow meters and controllers from the ES-FLOW series.

Ultrasonic Flow Meters & Controllers

Ultrasonic Flow Meter for liquids

Due to the combination of a straight sensor tube with zero dead volume, self-drainability, orbital TIG-welding and hygienic connections, this ultrasonic flow meter can be used for hygienic applications. Wetted parts are made of stainless steel, except for the rubber gaskets at the Triclamp or flange connections. The exterior design is according to IP66 as well as IP67. For non-hygienic applications, the instruments can also be equipped with compression type fittings.

The user interface is a capacitive touchscreen with a TFT display to operate and readout the instrument.

Liquid flow control

The ultrasonic flow meter can be connected to a dosing pump or a control valve to form a closed control loop. The electronic control function forms part of the normal circuitry in the meter.
