Oval Gear Flow Meter for Diesel/Gasoline, DN10-DN200

Note*: This flow meter is not equipped with explosion-proof certification. Caution is required when using it with flammable media.

Oval gear flowmeter belongs to a positive displacement flowmeter, in the flow meter is a class of high accuracy. The flow meter uses precision gears to make accurate measurements.

Specification

Features

• It is simple to install and easy to maintain.
• The scene showed zero back. The pointer indicates the flow, and the double value shows the single and cumulative flow respectively.
• The workmanship is exquisite. Multi-process construction, strong pressure resistance.

Dimension (unit: mm)

Detail

1. Scale Dial: Lightweight volumetric flowmeter with pointer display, word wheel totalizing device, and return-to-zero device.
2. Gear Rotor: The elliptical gear keeps rotating and discharging the liquid to get the total amount of liquid and instantaneous flow rate.
3. Flange Connection: It can make the product get better and more convenient maintenance in the later stage, and play the role of sewage, balance pressure.

Installation Diagram

Installation Precautions

• Horizontal Installation

1. Install the oval gear in a horizontal position as much as possible.
2. Install the meter at the output end of the pump body.
3. Install a filter in front of the meter to stop the passage of 0.2 mm microliter and prevent the meter from clogging.

• Vertical Installation

1. It is advisable to install a back valve in front of the meter so that only one-way flow is possible in the pipeline to prevent counter loss.
2. Installation can be from top to bottom left to right.

Application

Tips: Oval Gear Flow Meter Using Tips

• Clean the line. The new pipeline should be cleaned before operation, and often then washed with solid flow to remove residual welding chips, dirt, etc. At this time, the front and rear stop valves of the instrument should be closed to let the liquid flow through the bypass pipe. If there is no bypass pipe, install short pipe instead.
• Exhaust the gas. Usually after the solid liquid sweeps, there is still a lot of air left in the pipeline. With the pressure operation, the air flows through the positive displacement flowmeter at a higher velocity, and the movable measuring element may run too fast, damaging the shaft and bearing.
