Product Overview OF Circular gear flowmeter
The SHLEES circular gear flow transmitter is a volumetric flow transmitter. A transmitter for high-precision measurement of volumetric flow. As the medium flows, the gears mesh and rotate. Under the effect of fluid flow, a pressure difference is formed at the inlet and outlet ends of the instrument. Without power supply, a pair of gears rotate freely, and the cavity between the gears is filled with liquid. The liquid is discharged as it rotates. By measuring the number of revolutions of the gears, the flow rate of the liquid passing through the instrument can be known.

Advantages of the LW Circular Gear Flowmeter
Accurate Measurement at Low Flow Rates
The positive displacement measuring principle enables stable measurement when the liquid flow rate is low. This makes the flowmeter suitable for precise dispensing, chemical injection, lubrication and small-batch filling systems.
Suitable for High-Viscosity Media
The LW circular gear flowmeter can measure oils, resins, adhesives, inks, grease and other viscous liquids. Its measurement performance is less affected by changes in the flow profile than many velocity-based flowmeters.
High Repeatability for Dosing Control
Every gear rotation represents a defined liquid volume. The repeatable output signal can be used for automated filling, batching, proportioning and quantitative control processes where consistent delivery is essential.
Flexible Signal Output
Pulse output or analog output can be selected according to the control system. The flowmeter can be connected to a PLC, flow totalizer, batch controller or other monitoring equipment for real-time flow measurement and process automation.
Compact Installation
The compact measuring structure is suitable for installation in limited spaces, equipment skids and integrated production systems. Long straight upstream and downstream pipelines are generally less critical than with many velocity-based flow measurement technologies.
Installation Recommendations
Install the flowmeter according to the marked flow direction and ensure that the measuring chamber remains completely filled with liquid during operation. A filter should be installed upstream when the medium may contain hard particles or impurities, as solid contamination can increase gear wear or block the measuring chamber.
Avoid dry running and sudden pressure shocks. For high-viscosity liquids, the pipeline and medium may need to be heated before startup to reduce pressure loss and ensure stable flow.
FAQ-Circular gear flowmeter
What liquids can a circular gear flowmeter measure?
It can be used for hydraulic oil, lubricating oil, resin, glue, ink, fuel, solvents, edible oil and many other clean liquids. The exact configuration should be selected according to viscosity, temperature, pressure and chemical compatibility.
Is the circular gear flowmeter suitable for high-viscosity liquids?
Yes. Positive displacement gear flowmeters are commonly used for viscous liquids because they directly measure a fixed liquid volume during each gear rotation.
Can it be used for quantitative filling?
Yes. The pulse signal can be connected to a batch controller or PLC to control valves, pumps or filling equipment according to a preset volume.
Does the flowmeter require straight pipe sections?
Circular gear flowmeters are less dependent on the upstream flow profile than turbine, vortex flowmeters or electromagnetic flowmeters. However, installation requirements should still be confirmed according to the selected model and pipeline conditions.
Can the output signal be customized?
Pulse output and analog output options are available. Please provide the required signal type, power supply and control system information when requesting a quotation.
