2. Installation Notes
Transmitter’s configuration in accordance with the contract requirements, run the data set in accordance with
contract requirements. Users can check the meter nameplate to confirm that the instrument provided by the
model and instrument operating parameters set. It can be put into use after connect power. In order to ensure
your system run on normal operation, make sure that the sensor measurement is full of medium channels
Our company electromagnetic flowmeter is dedicated to conductive fluid (conductivity ≥ 5μS/cm, water ≥
20μS / cm) the volume of flow measurement.
Flowmeter installation and usage should be in strict accordance with the specification, and to comply
with the relevant national standards, safety requirements and accident prevention requirements.
MF7200 electromagnetic flow converter directly connected with the electromagnetic flow sensor
compact into one body
It should avoid large temperature changes. If the meter installed by the thermal radiation Plateau,
please provide the thermal isolation or ventilation. Instrumentation installed in the switch box,
there should be appropriate measures of net and ventilation are examples such as the fan.
Compact structure flow meter should give full consideration to the transmitter working environment
temperature.

It should avoid in a strong corrosive atmospheric environment. Installation location should have
adequate ventilation. Protective properties of instruments should be maintained to prevent the
corrosive gases and moisture into the instrument cavity. It Should avoid direct sunlight, especially
the liquid crystal display part. Strong vibration should be avoided.

3.) Installation methods
A compact body flowmeter transmitter and Sensor two parts is connected to the end before
out of factory, the user can be installed directly. Sub-constructer flowmeter for Transmitter and
sensors to be in two parts at field by the user through a dedicated cable (factory annex) to
connect. Part of the sensors installed on both glycosides, Transmitter are usually installed in
the indoor or meter box. The distance is shorter for better.
