Spire Mag888 电磁流量计

Features and Benefits:SpireMag Series MAG888 high-performance magnetic flowmeter accurately measures the flow volume of any conductive liquids, such as water, salt water, sewage, pulps, slurry, acid, alkali, or, any mixtures of liquids and solids which have a specific minimum of electric conductivity. SpireMag Series MAG888 has been widely used in municipal, wastewater treatment, irrigation,chemicals, as well as industrial liquid processes.Compared with other measurement methods, MAG888 electromagnetic flowmeter offers the following particular advantages:• No moving parts to wear and tear

• Short straight-pipe run required, thus, suitable for any desired installation location

• Plug and play. All parameters are pre-configured in factory

• Large turndown ratio, 1200:1

• No pressure loss

• Optional HART communication interface

• Self-diagnosing capability to minimize operational downtime

Accuracy: ±0.5% of reading. ±0.3% is available upon request.Damping Time Constant: 0～100s (90%) selectable.Display and Buttons: Large LCD display with backlight. Display the instantaneous flow, total flow, and alarm.Totalizer: Three built-in totalizers: forward flow totalizer, reverse flow totalizer and net totalizer.Output Signals:Analog output: Bi-directional, isolated 0～•10mA/4～20mA. Load resistor: 0～1.5ΚΩ for 0～10mA, 0～750Ω for 4～20mAFrequency output: Forward & reverse flow output with the frequency range of 1～5000Hz. The external voltage must be lower than 35V and the max output current must be 250mA when the transistor is turned on.Alarm output: Two isolated Open Collector Transistor (OCT) outputs for alarm signals. The external voltage must be lower than 35V and the max output current must be 250mA when the transistor is turned on. Alarm will be activated when the pipe is empty, the excitation circuits are broken or the volume of flow rate exceeds the value of designed limits.Pulse output: the OCT circuit is used for forward or reverse flowrate output. The upper frequency of the output pulse can be up to 5000cp/s. The relevant value of pulse is from 0.0001 to 1.0m3/cp. Pulse width can be set to 20ms or 50% occupancy. The external voltage must be lower than 35V and maximum output current must be 250mA when the transistor is on.Communication: RS232C, RS485 or HART Communication selectable.Power Failure: An anti-failure clock is built into the flow meter, which can save the power failure records for 16 times.Protection ClassFor electronic box: IP65 (outdoor)For sensor: IP65 (outdoor) or IP68 (submersible, only for remote type)Nominal Pressure: 0.6～4.0MPaLining Material: Rubber, PTFE, Polyurethane, PFAElectrode Type: General type, scraper type or replaceable typeElectrode Material: 316L SS, Hastelloy B, Hastelloy C, Titanium, Tantalum, Platinum-iridiumMedium Temperature:Integral type:-10°C～+80°CRemote type: Neoprene & Polyurethane Liner -10°C～+80°C; PTFE, PFA, F46 Liner -10°C～+160°CAmbient Temperature: -25°C～+60°CAmbient Humidity: 5～100%RH (relative humidity)Medium Electrical Conductivity: ≥15us/cm standard. ≥5us/cm upon requestMeasuring Range: 1500:1, flow rate≤15m/sStructure Type: Integral type, remote type, submersible type, ex-proof type
