Detailed Product Description: | Technical information Proline Promag 10W Electromagnetic flow measurement system For water and sewage industry in the fluid flow measurement Application Promag 10W electromagnetic flow meter two-way measurements of the conductivity ≥ 50μ S / cm of fluid flow. ? Drinking water ? Wastewater ? Sewage sludge ? Medium flow rate of up to 110,000 m3 / h ? Medium temperature up to +80 ° C ? Process pressure up to 40 bar ? Assembly length: in accordance with DVGW / ISO standards Measuring tube a special lining material:? Polyurethane hard rubber Measuring tube lining material meets the certification requirements of the drinking water industry: ? The KTW, WRAS, NSF, the ACS Advantage Promag electromagnetic flow measurement system provides a cost-effective flow Measurement program, high accuracy, wide measurement range. The P rolin e transmitter features: ? High reliability, high measurement stability ? Endress + Hauser unified operating concept P romag sensor characteristics: ? No pressure drop? Is not sensitive to the pipe vibration ? To install and convenient debugging TI093D / 28/zh/06.05 / (02. 09) Measurement principle Measurement system Measured variables Measuring range Turndown ratio Proline Promag 10W Function and system design According to Faraday's law of electromagnetic induction, the conductor in a magnetic field generates an induced voltage. , The application of electromagnetic induction principle to measure the flow of the conductive medium is equivalent to the law of the moving conductor. The size of the induced voltage is proportional to the flow rate of media, two measuring electrodes detect the induced voltage signal and sent to the amplifier for amplification. According to the cross-sectional area of ??the pipe to calculate the volume flow of the medium. Switched direct current of alternating polarity will result in a dc magnetic field. Ue induction voltage B magnetic induction (magnetic field) L two measure the distance between the electrodes v medium flow rate Q volume flow A pipe cross-sectional area I current intensity The measurement system consists of transmitter and sensor. The two structure types to choose from: ? Integration version: transmitter and sensor form an integral mechanical unit as a whole. ? Separation type: sensor and transmitter separate installation. Transmitter: ? Promag 10 (button operation, two line backlit display) Sensor: ? Promag W (DN25 ... 2000) Enter Medium flow rate (proportional to the induced voltage) Liquid in the measuring range The specified measurement accuracy, the typical value of v = 0.01 ... 10m / s > 1000: 1 Endress + H Output Output signal current output ? Electrical isolation ? Active: 4 ... 20 mA, RL <700Ω (HART: RL ≥ 250 Ω) ? Full scale value selectable ? Temperature Coefficient: Typical value 2μA / ° C, resolution: 1.5μA Pulse / status output ? Electrical isolation ? Passive: 30V DC/250mA ? Open collector? Can be set as follows: - Pulse output: pulse value and pulse polarity selectable, maximum pulse width adjustable (5 ... 2000ms), the maximum pulse frequency of 100Hz - Status output: for example, fault messages, empty pipe detection, flow identification and limits set Alarm signal? Current output → failure protection mode is optional ? Pulse output → failure protection modes are available ? State output → system error or power failure, manifested as "open state" Load reference output signal Low flow cut off according to the need to select the low flow cutoff switch point. Electrically isolated from the input signal, the circuit between the output signal and power mutual electrical isolation. Power supply Electrical connection of the measuring unit Connection of the transmitter (aluminum field housing) cross-sectional area of ??the cable up to 2.5mm2. a electronic wiring cavity cover b Electricity Supply Lines c power supply cable ground d connecting the power cable terminal blocks e signal cable f signal cable ground g connection signal cable terminal blocks h service interface i instrument ground 3 |
