DIRECT ANSWER

Where does Positive Displacement Flowmeters fit?

Select positive-displacement gear flowmeters using liquid identity, viscosity, flow range, pressure, temperature, pressure loss, process connection and output.

Prepare these four inputs
  1. Measurement task and medium
  2. Operating range and upset conditions
  3. Mechanical installation and materials
  4. Power, output, communication and documents

TYPICAL MEDIA

Start with what is being measured

Use the medium and operating conditions to narrow the suitable measurement principle and construction.

Viscous liquids

Provide viscosity at minimum and maximum temperature.

Low-flow duties

State stable minimum flow and required response.

Hydraulic and dosing systems

Confirm pulsation, pressure and cleanliness.

SELECTION FACTORS

A practical four-step selection brief

Use these steps to prepare a useful quotation request without guessing a model.

  1. 01

    Map viscosity

    Provide the operating viscosity range, not only liquid name.

  2. 02

    Define flow range

    State minimum, normal and maximum flow.

  3. 03

    Check pressure conditions

    Include line pressure, pressure loss and pulsation.

  4. 04

    Confirm interfaces

    Specify process connection, power, output and display.

FAQ

Positive Displacement Flowmeters measurement questions

These answers match the visible selection guidance and do not replace model-specific technical review.

When is a gear flowmeter considered?

It may suit compatible liquid duties where a positive-displacement measuring chamber matches the viscosity, range and pressure conditions.

Does viscosity affect selection?

Yes. Viscosity can affect measuring range, pressure loss and mechanical performance.

Are solids acceptable?

Particles can cause wear or blockage, so cleanliness and filtration must be reviewed.

APPLICATION-LED QUOTATION

Send the operating conditions, not just a product keyword

Include the measured variable, medium, range, pressure, temperature, installation, output, quantity and destination. The quotation can then record the proposed model and supply scope.
