Gas Industry Mass Flow Meter

Sealand is a trustworthy manufacturer of Gas Mass Flow Meter, Gas Mass Flowmeter, Gas Flow Meter, Gas Flowmeter, Gas Meter, ATEX, IECEx & CE approved.



The installation is as follows.

1. Installation Steps
a) Choose correct installation site, taking installation area, pipeline, transmitter location &

valve location into consideration;
b) Install the meter according to direction mark on sensor; c) Install the sensor & transmitter on pipeline;
d) Connect transmitter & sensor with 9-pin cable;
e) Start.


2. Site selection

a) Sensor stays away from mechanical vibration source, for example, pump. Use flexible pipe to connect meter with pipeline if inevitable. The housing of meter must be standalone, out of touch with any other device. There must be 3 times the size of sensor between 2 sensors if there are many flow meters on the same pipeline, to avoid resonance.

b) Do not install sensor on pipeline that easily expands with hot and contracts with cold, especially near expansion joint, which leads to a worse stability.

c) Sensor stays away from industrial electromagnetic field, such as large generator and transformer, better 5m at least. Such device influences the performance of drive coil and pickoffs. Make sure magnetic field intensity less than 400A/m.

d) Sensor shall be installed on lower pipeline, to be easily full of fluid.
e) Make sure Ex-mark meet application requirements if in hazardous area.

f) Build a sunshade if the meter is under direct solar radiation. g) Keep the meter from corrosive liquid.
