Introduction

Oval gear flowmeter is a volumetric measuring instrument for continuous or intermittent measurement and control of liquid flow in pipelines. It has a large range, high accuracy, small pressure loss, viscosity adaptability, can measure high temperature and high viscosity liquids, convenient calibration, installation recommendations and many other advantages. It is suitable for flow measurement in petroleum, chemical industry, chemical fibre, traffic, commerce, food, medicine and health and other departments.

ATLC series oval gear flowmeter is equipped with pointer and word wheel accumulation device, which can directly display the cumulative flow of the liquid flowing through the pipeline. In the counting mechanism attached to the sending device and electric display instrument supporting the cumulative, quantitative and instantaneous flow rate can be achieved by remote centralised control. Add a radiator or elliptic wheel owes teeth can measure high temperature, high viscosity liquid.

Different liquids (acid, alkali, salt, organic solutions, etc.) flowmeter body can choose different materials.

Features

High Accuracy: Oval gear flowmeters offer precise measurement capabilities, making them suitable for applications where accurate flow measurement is critical.

Wide Viscosity Range: They can measure fluids with varying viscosities, from thin liquids to highly viscous substances, without significant loss of accuracy.

Low Pressure Drop: Oval gear flowmeters typically have a low-pressure drop across the meter, minimizing energy loss and maintaining system efficiency.

Bi-Directional Flow Measurement: Many oval gear flowmeters can accurately measure flow rates in both directions, providing flexibility in applications where flow direction changes.

Compact Design: They often feature a compact design, making them easy to install in space-constrained environments or within existing piping systems.

Minimal Maintenance Requirements: With their simple design and few moving parts, oval gear flowmeters require minimal maintenance, reducing downtime and operational costs.

Durability: Constructed from robust materials such as stainless steel or engineered plastics, oval gear flowmeters are durable and resistant to corrosion, ensuring long-term reliability.

Digital Output Options: Modern oval gear flowmeters often come equipped with digital output options such as pulse, analog, or digital communication protocols, enabling seamless integration with control systems and data logging equipment.

Installation

1. A matching filter should be installed before the flowmeter, and the outlet of the matching filter should be immediately connected to the inlet of the flowmeter, and the arrows on the two bodies should point in the same direction as the liquid flow.

2. When the measured liquid contains gas, a degassing filter should be installed before the flowmeter.

3. Regardless of whether the pipeline is vertical or horizontal installation, but the flowmeter in the elliptic gear should be installed into a horizontal position (i.e., the dial should be perpendicular to the ground).

4. flowmeter in the correct installation, if it is not easy to see the reading, the counter can be turned to 180 degrees or 90 degrees can be.

5. new flowmeter before installation with a bamboo stick from the outlet of the elliptic gear pushed a few times, such as the discovery of immobility, can be soaked in diesel fuel (to avoid factory calibration of the memory of sediment).

6. flow control valve should be installed in the flowmeter inlet, open and close the valve is installed in the outlet, the use of open and close the valve slowly start, do not suddenly open in order to prevent "water shock" phenomenon.

7. in the new pipeline before the installation of the flow meter, the pipeline needs to be flushed, flushed with a straight section (instead of the location of the flow meter) to prevent weld slag, debris, etc. into the flow meter.

8. is strictly prohibited water calibration cast iron, cast steel material flow meter.

9. flowmeter in use when the flow size shall not exceed the technical requirements. Flowmeter working at the maximum flow rate of 50-80% is preferred.

10. If the measured liquid is chemically corrosive, the flowmeter must be made of stainless steel.
