1. Sewage flow meter advantages: (1) The measurement channel of the waste water flow meter is a smooth straight pipe with no obstructing flow detection element. It is not easily obstructed and is suitable for measuring liquid-solid two-phase fluids containing solid particles or fibers such as pulp, coal water slurry, pulp, mud and sewage. Wait. (2) The sewage flow meter does not generate pressure due to the detected flow rate Loss, instrument resistance is only the resistance along the same length of the pipeline, energy-saving effect is significant, for the demand for low resistance loss of the largest diameter water supply pipeline is most suitable. (3) The volumetric flow rate measured by a sewage flow meter is virtually independent of changes in fluid density, viscosity, temperature, pressure, and electrical conductivity (as long as it is above a certain threshold). (4) Compared with most of the other flow meters, the straightforward pipe section requires less. (5) The daily range is large, usually 20:1 to 50:1, with a wide range of flow options. (6) The scope of the diameter of the sewage flow meter is wider than other types of flow meters, from a few millimeters to 3 meters. Measurable positive and negative two-way flow, can also measure pulsating flow, as long as the pulsation frequency is much lower than the excitation frequency. Instrument output is essentially linear. (7) The variety of materials that are easy to select with the fluid contact can be applied to corrosive fluids. 2. Sewage flowmeter disadvantages: (1) Sewage meters cannot measure liquids with very low electrical conductivity, such as petroleum products and organic solvents. Can not measure gas, steam, and liquids containing more large bubbles. (2) General-purpose EMFs cannot be used for higher temperature liquids because of the restrictions of lining materials and electrical insulating materials: Some models use liquids that are used at or below room temperature, and damage the insulation due to condensation or frost on the outside of the measuring tube.
