DLY series of electronic nozzle with flowmeter (abbreviated as oil-filling gun) is a meter used to measure the volume flow rate

DLY SERIES OF ELECTRONIC NOZZLE WITH FLOWMETER

I. Usage

DLY series of electronic nozzle with flowmeter (abbreviated as oil-filling gun) is a meter used to measure the volume flow rate of liquid passing through the pipe. It is suitable for measuring gasoline and kerosene fuel etc. The meter has such advantages as high accuracy and convenient and flexible use. As long as there is a height difference of 2m to 10m between the liquid level of measured medium and the meter, it can operate normally without any additional power source.

II. Main technical parameters

1. Nominal diameter and flow rate:

Model	Nominal diameter (mm)	Minimum Flow rate (L/min)	Rated flow rate (L/min)	Maximum flow rate (L/min)	Display value of meter	Accumulated value
DLY-25 model	25	25	35	60	0.1~9999.9	0.1-9999999.9
DLY-32 model	32	32	60	100	0.1~9999.9	0.1-9999999.9

2. Metering accuracy: ±1%

3. Measured medium: gasoline. If the medium is kerosene or diesel oil, the readings of flow meter shall be corrected. Refer to article 5 of clause 4 for details.

4. Maximum working pressure: 0.1MPa

III. Main structure and working principle

The electronic nozzle with flowmeter is composed of electronic digital displayer, metering chamber and main body etc. three parts. Among them, the electronic digital displayer is composed of magnetic coupler, accumulation indicator and zero-resetting device etc. mechanism. The metering chamber is composed of core rack, impeller, worm wheel and worm. The main body is composed of meter shell, oil inlet and outlet tank and valve mechanism etc.

Grasp firmly the bending handle. When the valve opens, the liquid will pass through the oil tank and flow into the metering chamber, and under the action of liquid, the impeller will produce torque to rotate. The rotation speed of impeller will be reduced by worm wheel, worm and gear, and driven by the magnetic coupler, the electronic digital displayer will carry out calculation, so that the volume quantity of liquid passing through the pipe can be read out.
