What is a sewage meter?According to Faraday's law of electromagnetic induction, volume flow of conductive medium inside the induction tube is calculated to calculate flow volume. Embedded microcontroller technology is adopted to realize digital excitation. Meanwhile, CAN field bus is adopted on the sewage meter to test the sewage meter.Now let's talk about the benefits of the sewage meter.

First,the sensor of HNFS sewage flowmeter is simple in structure. There are no moving parts in the measuring tube, nor any throttling parts that hinder the flow of fluid.Therefore, when the fluid passes flow time, it will not cause any additional pressure loss, and it is one of the flow meters with the lowest energy consumption in the flow meter.

Second, the flow rate of the dirty medium, corrosive medium and suspended turbidity liquid and solid phase flow can be measured.This is because there are no obstructed flow components in the measuring tube, and only the inner lining and electrode of the measuring tube are contacted with the measured tube, and the material can be selected according to the properties of the measured tube.For example, with polytrifluoroethylene or polytetrafluoroethylene lining, can measure various acid, alkali, salt and other corrosive media;The inner lining of wear resistant rubber is especially suitable for the measurement of liquid and solid two-phase flow such as slurry and cement slurry with solid particles and various suspensions such as fiber liquid and pulp.

Thirdly, HNFS sewage flow meter is a kind of volume flow measurement instrument. During the measurement, it is not affected by the temperature, viscosity and density of the medium under test in terms of electrical conductivity (within a certain range).Therefore, the sewage flowmeter can be used to measure the flow of other conductive liquid only after water calibration.

Fourthly, the output of HNFS sewage flowmeter is only proportional to the average flow velocity of the medium under test, but independent of the flow state (laminar or turbulent) under symmetrical distribution.Therefore, the range of electromagnetic flowmeter is very wide, and its measuring range is up to 100:1, and some even up to 1000:1 operating flow range.

Fifth,no mechanical inertia, sensitive response, can measure instantaneous pulsation flow, also can measure the flow in both directions.

Sixthly,the diameter range of HN series sewage flowmeter for industrial use is very wide, from a few millimeters to several meters, and the existing solid flow calibration equipment with diameter up to 3m in China has laid a foundation for the application and development of electromagnetic flowmeter.
