LPG gas mass flow meter

Visualization of the unloading volume of liquefied petroleum gas tank trucks into storage tanks.

Protect the interests of gas station employers to avoid being deceived by gas suppliers.

Installation requirements：

I. Mass flow meters work on the principle of vibration, so the installation location

should be as free from vibration as possible and the installation pipework should

be securely supported. If the source of vibration is unavoidable, it is

recommended to use a hose connection. The connection line and the instrument

interface should be located in the same axis, not to impose an additional force on

the instrument. Unnecessary additional forces can have an impact on the

measurement accuracy of the instrument.

II. If the gas content in the liquid is high, a gas-liquid separator must be added at the

front of the flowmeter inlet, otherwise it will have an effect on the measurement

accuracy.

III. Throttling devices, such as flow control valves must be installed at the outlet of the

flowmeter.

IV. Flowmeter inlet and outlet should be equipped with shut-off valves to facilitate

zero calibration after initial installation.

V. The flow meter should be appropriately far away from the outlet of the pump,

especially reciprocating pumps, etc., the installation distance is too close and may

cause fluctuations in the flow measurement value.

VI. Installation direction: Make sure that the direction of the arrow on the nameplate

2of the sensor is the same as the direction of fluid flow (the direction in which the

fluid flows through the pipe).

VII. Sensor and transmitter number should be one-to-one correspondence, not

arbitrary replacement, or may produce measurement errors

VIII. If the flowmeter is installed outdoors, it is recommended to install a rain shelter

for the transmitter and tighten the front and rear covers of the flowmeter, and to

ensure that the electrical connector position seals are intact to prevent water

ingress into the transmitter.

IX. Recommends that the commonly used volume be at least 1/3 of the meter’s

standard range and that the user’s minimum flow rate be at least 1/10 of the

meter’s range.
