5 ELECTROMAGNETIC FLOW METER EPD electromagnetic flow meter is a highaccuracy flow meter manufactured based on the latest international technology. It is widely applied in papermaking, chemical industry, metallurgical industry, drainage, waste water treatment, liquid highpressure metering, medical care, food, and environmental protection industries. It is used to measure the nonmagnetic liquid and plasma in the enclosed pipe. WORKING PRINCIPLE The working principle of the electromagnetic flow meter is based on the Faraday law of electromagnetic induction. When the conducting liquid flows in the orthogonal direction of the magnetic line direction, it will cut the magnetic lines and generate induced voltage, which shows linear relationship with the flowing speed. Thus, the fluidic volume flow can be calculated. EPD electromagnetic flow meter is mainly composed of the sensor and transmitter. The measuring tube of the sensor is equipped with the excitation coils upward and downward. The transmitter supplies the excitation current, which generates the magnetic field which goes through the measuring tube once it is powered on. A pair of induction electrodes installed on the inner side of the measuring tube comes in contact with the liquid to guide the induced voltage to the sensor. FEATURES The measurement results are not affected by the change in liquid density, viscosity, temperature, pressure and conductivity. Powersaving and low fault rate: The measuring tube is without baffle and movable parts, so it won t cause pressure loss and jam. It can be widely applied in the conducting liquids that may contain fiber, solid granules and suspended matters. It is easytoinstall with low requirements for the straight tube section (Front D and rear 5D). The wide measurement turndown ratio can reach :00, which can be set randomly and achieve high accuracy for small flow measurement. Protection rating: Integrated type DN0~DN00 (IP67/NEMA X) Highlyintegrated backlit display of two rows, dual isolation, parameter setting, menutype operation, memory function, reliable programming, password lock and access, small signal elimination, nonlinear correction and twoway measurement. Smart selfdetection and selfdiagnosis function, as well as various alarms. Various outputs: Current output ~0 ma/0~0 ma, frequency output ~khz and RS5 communication. Various options of bushing and electrode material, applicable to different media. APPLICATIONS Waste water treatment Tapped water purification Sewerage Sea water desalination module Dyeing machines Solar energy and PCB wet processing Food manufacturing Pharmaceutical machines

7 MATERIAL SELECTION Electrode material Electrode material Stainless steel (6L) Hastelloy alloy Anticorrosion property It is applied in water, sewage and organic and nonorganic corrosive medium. It is resistant to the corrosion of the medium mixture of oxidizing acid such as Nitric acid, mixed acid or Sulfuric acid. Moreover, it is resistant to the corrosion of the + + oxidizing salt such as Fe Cu or other substances containing oxidants such as the salt solution of hypochlorous acid above the ambient temperature and sea water. Titanium It is resistant to the corrosion of sea water, various oxides, salt solution of hypochlorous acid, oxidating acid (including fuming Nitric acid) and organic acid and alkane. It is not resistant to the corrosion of pure reducing acid (such as Sulfuric acid and Hydrochloric acid). However, the anticorrosion property will be greatly degraded if the acid contains some oxidants. Bushing material Bushing material PTFE Main properties. Stable chemical properties, resistant to various acid, alkane, and salt solutions and various organic solvents. It is not tolerant to the corrosion of CIF, hightemperature OF and highspeed liquid oxygen and ozone.. The antiabrasion property is average. Application scope. 0~0BC. Strong corrosive medium such as concentrated acid and alkane.

10 INSTALLATION INSTRUCTIONS. The flow meter must be free from strong electromagnetic field. The magnetic intensity of the flow meter installation site must be smaller than 00A/m (It should not be installed near large motors or transformers).. It should be installed at the lower point and the vertically upward point of the horizontal pipe. Don t install it at the highest point and the vertically downward point of the pipe.. It should be installed at the rising point of the pipe.. It should be installed at the lower point of the pipe when it is installed on the pipe with opening for drainage. 5. If the pipe gap exceeds 5m, the air release valve should be installed at the downstream of the sensor. The downstream of the sensor should have some back pressure. Air Release Valve 6. The control valve and cut valve should be installed at the downstream of the sensor rather than the upstream. 7. The sensor should be installed at the pump outlet rather than the inlet.. The fluidic must flow towards the arrow direction of the flow meter. 9. The axial line of the measuring electrode must be approximate to the horizontal direction (The angle of from the horizontal direction). 0. The measuring pipe must be completely filled with liquid. 6

11 . The straight tube section is required to be at least 5D (internal diameter of the flow meter) on the front side, and at least D on the rear side.. When measuring the mixture of different media, the distance between the mixing point and the flow meter must be 0D at least.. For convenient cleaning and maintenance of the flow meter, a bypass pipe must be installed.. When installing the sensor, it should ensure that the measuring pipe and the process pipe must be on the same axial line. For the flow meter with the pipe meter of 50mm or below, the axial line deviation should not exceed mm. For those of DN65~DN50, the axial line deviation should not exceed mm. For those of DN00, the axial line deviation should not exceed mm. 5. The shim installed between the flanges should have excellent anticorrosion property. The shim should not intrude in the pipe, which will affect the fluidic in the pipe. 6. The sensor and transmitter should be equipped with highquality independent grounding wire (The section area of the copper core is.6mm). The grounding resistance should be <0Ω. If the grounding is poor, it won t work normally. The grounding ring is needed if the pipe connecting with the sensor is insulating, and the material of the grounding ring should be the same as that of the electrode. If the test medium is abrasive, the neck grounding ring should be selected. 6. It is for installing the flow meter on the metal pipe not coated with insulating layer internally. 6. When installing the flow meter on the protective pipe of the cathode, the pipe with the protection of electrolytic corrosion generally has insulating walls and protruding sides. Thus, during installation, the grounding ring and the flanges on the pipe should be insulating. 6. When installing the flow mater on the plastic pipe or the pipe with insulating coating material, paints or bushing, grounding rings on both ends of the sensor should be installed. 7
