FAQ

Do the nozzles need to be calibrated or replaced regularly? How long is their lifespan approximately?

The lifespan depends on the material. For instance, the PVDF material used in our nozzles can  lasts approximately three to five years.It also depends on the specific situation.


After the nozzle has been in use for a period of time, the measured values show a systematic deviation (such as consistently being lower than the actual value). What could be the possible reasons for this?

Blockages, corrosion and wear and tear can all affect the accuracy.

How to select a flow meter?

Select based on the medium, temperature, pressure, flow range and accuracy requirements. For clean and low-viscosity fluids, choose paddle wheel flow meter; for large pipe diameters or strong corrosive substances, choose ultrasonic flow meter; for medium to small flow rates or for on-site display, choose rotor flow meter.


Why choose to trust Mid-crown Fluid Technology.,Ltd?

With multiple core patents as support, the technical barriers are profound. The performance of our flow meters and nozzles leads the industry, precisely addressing the pain points in industrial fluid scenarios.


If the reading of the paddle wheel flow meter suddenly becomes low or the impeller doesn’t rotate, how to troubleshoot?

Possible causes and solutions:

1. Impurity blockage:Particles in the fluid get stuck in the impeller.It’s necessary to remove and clean it,and install a filter.

2. Bearing wear:After long-term use,mechanical wear occurs.It’s necessary to return to the factory to replace the core components.

3. Signal system failure:Check if the magnetic coil is damaged,or if the signal line is not in good contact.

4. Low flow rate: The flow velocity is lower than the startup flow rate of the instrument,and the impeller cannot rotate.


Why might the ultrasonic flow meter not measure accurately or have unstable signals?

Possible reasons include:

1.Pipeline conditions do not meet requirements:

 The inner wall of the pipeline is caked with deposits, the lining is too thick or the material is inconsistent, which affects the transmission of ultrasonic waves.

2. Incorrect installation location: The measurement point is too close to the valve, pump or elbow, and the fluid is not fully stabilized.

3.Probe installation issue: Insufficient coupling agent, incorrect probe spacing or misalignment, resulting in weak signal strength.

4.Medium problem: The fluid contains bubbles, solid particles or has an excessively low flow rate, which exceeds the range of the instrument.


Who are we? What can we do for you?

We are a Chinese manufacturer of fluid system components, specializing in nozzles and flowmeters for PCBs, LCDs, and semiconductor equipment. We have independent R&D capabilities and support customized requirements.


How to customize a desired nozzle

Confirm the flow rate, angle, material, injection type, interface size, integrated or split type you need, and produce samples after submission.


How to correctly select the required rotor flowmeter model?

Measure the maximum outer diameter of the pipe, select the model with the fitting diameter that fits the pipe in the product manual, and confirm the interface method and specifications.
