Different Types of Oval Gear Flow Meters you should know

The gear flow meter belongs to a kind of volume flow meter and can be used for the exact measurement of the liquid volume flow. The liquid causes the gear to snap into place and rotate. Under the influence of the fluid flow, a pressure difference is formed between the input and the output of the gear flow sensor. A pair of gears can rotate freely without the need for a power supply. The empty cavity between the gears is filled with liquid that escapes through the rotation. The fluid flowing through the instrument and the fluid can be determined by measuring the speed of the gear.

The oval gear flow meter made of aluminum alloy can withstand a maximum pressure of 15 MPa, the stainless steel gear flow meter can withstand 40 MPa. The standard operating temperature of the liquid: -15-80°C, the special requirement of the liquid temperature: -196°C ~ 200°C. High precision: 1:10 variability, the precision is 0.5%; Range1: 100, the accuracy is ±1.0% The current output/pulse output is available.

Excellent turndown ratio (1:100).

Large measuring range.

It can measure different types of viscous liquids and can measure liquids at 10,000 mPa.s It can be used to measure corrosive or aggressive liquids by selecting different materials.

Features As a kind of new volume flow meter, the gear flow meter is used to accurately measure the flow or instantaneous liquid flow within the pipeline in both a continuous and discontinuous flow.

It is particularly suitable for measuring heavy oil. Flow measurement of liquids with high viscosity such as vinyl and resin. (It can be used to measure the liquid whose viscosity reaches 10,000 mPa.s) The transmission flow meter has a small volume, lightweight, low operating noise, and stable operation. It can also be used to measure the micro flow of the small pipe diameter. With a reduced initial flow and a wide range, it is applicable to measuring liquid flow with significant changes, and its measurement accuracy is not affected by the change in pressure or flow. It is stable in terms of performance, long life and large circulation capacity.

Oval gear digital meter The oval gear digital meter uses mechanical measuring elements to continuously divide the liquid into a single part of the known volume and to measure the total flow volume based on the frequency with which the measuring chamber fills the part of the liquid volume and dispenses one by one. Gear flow meters can be made from various materials (cast iron, cast steel, stainless steel 304, and stainless steel 316) and are suitable for flow measurement in industrial areas such as chemistry, oil, pharmacy, energy, metallurgy, and food.

Oval gear flow can send 4~20 mA signals, pulses, etc. Communication protocols include HART and MODBUS etc.

The oval gear meter is suitable for measuring different media and can be used as a highly viscous flow meter.

The oval wheel meter does not require a straight hose when installing the oval wheel flow sensor.

Oval flow meter made of stainless steel The oval gear flow meter is a type of PD flow meter that constantly measures the liquid. The oval meter can also be converted in digital form into a mechanical oil flow meter with various outputs (4-20 mA, pulse, RS485), etc. for various measurements or control purposes. The electronic flow meter for display, monitoring, transmission, and control is becoming increasingly popular.

Our customers often need a stainless steel displacement flow meter when measuring liquids such as vegetable oil, cooking oil, fat, resin, pastes, syrups, clean water, aggressive liquids, and chemical liquids, etc, bought for the sanitary and hygiene industry or for the pharmaceutical industry. The robust design offers perfect and continuous performance in harsh environments.
