Flow direction. Micro Motion sensors measure accurately regardless of flow direction. Flow direction arrow The sensor features a flow direction arrow (see illustration below), but the sensor will measure flow in either direction. If the process fluid flows in the direction opposite to the flow direction arrow, flowmeter outputs might not behave as expected unless the transmitter is configured ...

A flow direction sensor was fabricated by MEMS (Micro Electro Mechanical Systems) technologies. Pt (Platinum) was sputtered on a silicon wafer and patterned by photolithography and a liftoff process. In addition, a silicon diaphragm was formed by backside etching. The structure of the designed sensor, which consists of one heater and four detectors, is a circulartype that can obtain uniform ...

The flow direction for the sensor is clearly marked on the label. Do not reverse the flow direction or the unit will not function. Close Up of Label Showing Flow Direction (FLR 1000 shown, other models similar) For the best results precautions should be taken to minimize the amount of turbulence in the flow stream. Avoid valves, fittings ...

The FDX Series Clampon Micro Flow Sensor can be easily installed from outside the pipe and detect flow rates as low as mL/min (and shot amounts as low as mL). The device does not come into contact with the liquid, preventing problems such as pressure loss and clogging. The noncontact design also means the device is not affected by the properties of the liquid (ex. viscosity). Even ...

A flowdirection microsensor is constructed by arranging eight cantilever structures on an octagonal platform. Each cantilever is separated from its neighbors by a tapered baffle plate connected to a central octagonal pillar designed to attenuate the aerodynamic force acting on the cantilever beams. By measuring the resistor signals of each of the cantilever beams, the microsensor is capable ...

First, an ultrasonic sensor was manufactured by selecting the matching layer with consideration of the acoustic impedance. In the experiment, a mass flow controller (MFC) was attached to a perforated hole in the fabricated chamber to generate microleakage, and the signal from the receiving ultrasonic sensor was then collected. The envelope ...

The flow sensors are always somewhat directionally sensitive. This is because it is impossible to build the sensor completely symmetrically. Thus, you either need to know the direction of flow in your system and calibrate in the same direction, or you operate with substantial uncertainties, especially at high velocities. You need a dedicated calibration setup preferable consisting of a system ...

In the flowrate/flowdirection sensor developed in this study (see Fig. 2), the pillar in the center of the octagonal platform serves as a windbreak to reduce the aerodynamic forces acting on the microcantilever beams facing into the wind in order to prevent them from cracking under the effects of an unsustainable load. However, a poorly ...
