The new rotor type water meter, in dripping water, if the drip is very slow, for example, 10 minutes a drop, the water meter will turn? Do not know the reason, please do not answer, please explain the reason!
The new meter adds a cavity in the bottom case, and is connected with the water outlet, the middle with a soft diaphragm separated, and adding a valve at the outlet, when the outlet to drip out water, down to the deformation of soft membrane in the inlet pressure under the action when the water reaches a certain amount, drip proof device will open the outlet pressure, so as to drive the impeller to rotate to measure the effect process of water supplement is intermittent, measurement in the process of water leakage is intermittent. When the normal water valve, the sensor will follow the open, so that the water becomes a completely ordinary water meter.
However, the actual situation of reducing water exists only in the old mechanical water meter, because the function to prevent Paomaodilou increase in new water meter, the negative deviation probability is low.
The use of the old mechanical water meter, because the rotating parts and counting gear movement in the rotor type water meter running in the presence of inertia, when the water flow is low, cannot promote the movement of the impeller and the counter gear error will be sharply biased, that will reduce the actual water content measurement.
