Sixth, the waste water meter installation instructions:

In order to correctly measure, the choice of pipeline location should note the following requirements:

(1) The sensor can either be installed on a vertical pipe can also be mounted on a horizontal or inclined pipeline, but requires two electrodes center connection is level;

(2) media during the installation position should ensure full pipe flow, to avoid discontent and gas pipe attached to the electrode;

(3) For the liquid-solid two-phase fluid, preferably mounted vertically, so that the sensor is uniformly lining friction and prolong life;

(4) When the meter installation media is dissatisfied pipe, can be taken to raise the rear end of the flow pipe line method to make full pipe, the highest point in the pipeline is strictly prohibited and outlet flow meter is installed;

(5) Modify the pipeline installation method:

When the medium flow rate below standard, the meter should be selected smaller diameter, then you should use conjugated tube diameter or modify part of the pipeline, so that the sensor of the same caliber, but around the straight section must at least meet the former straight pipe ≥ 5DN, after the straight pipe ≥2DN;

(6) the length of straight pipe before and after meter before ≥5DN, backend ≥2DN;
