Intelligent electromagnetic flowmeter price, manufacturer, lowest WF series electromagnetic flowmeter has an excellent design. Qingdao Wan An electromagnetic flowmeter uses low frequency square wave excitation, with good output stability. Its excitation mode and a variety of linings, decided it has wide range of applications. The main features of Qingdao Wan An electromagnetic flowmeter can respond quickly and have good stability precision, especially up to 0.5% calibration wide temperature range high-resolution backlit LCD display for easy operation with a RS485, RS232C, HART, MODBUS and other bus digital communication output capable of bi-directional flow measurement, the total cumulative performance bidirectional I, converter flow measurement range of the sensor package, the flow velocity measurement range can be selected in the limits 0.3m / s ~ 15m / s within the range limit velocity values ??for the current output of 1% upper limit of the current output signal: Full isolated 0 ~ 10mA / 4 ~ 20mA load resistance: 0 ~ when 10mA, 0 ~ 1.5kΩ; 4 ~ 20mA when, 0 ~ 750Ω basic error: plus ± 10μA output frequency output frequency limit can be set in 1 ~ 5000Hz within the measuring basic error basis. The frequency output with optical isolation transistor open collector output. External power is not greater than 35V, maximum collector current of 250mA when conducting pulse output flow indication / range indication output of the meter can measure the flow rate of fluid flow positive and negative directions, and can determine the direction of fluid flow. Provides display output 0V when low forward flow, reverse fluid flow output + 12V high level. Automatic dual range switching applications, the first range (high range) output + 12V high, second range (low range) output 0V low. Alarm status: Flow limit alarm, low alarm communication optional RS232C, RS485, HART and MODBUS communication options, damping time 0 ~ 100s (90%) between the sub-file options can also play a remote clearing the counter. Display can show the value of the instantaneous flow totalizer flow in both directions of traffic and the percentage of self-diagnostic function converter failure, the measuring tube failure to know and displayed within the electrical interface M20'1.5 threaded aluminum converter housing material protection class IP65 electromagnetic flowmeter contact dielectric material lining: rubber, PTFE and PFA electrodes: 316L stainless steel, Hastelloy C, titanium, tantalum and platinum grounding rings / grounding electrodes: 316L stainless steel, Hastelloy C, titanium, tantalum and platinum normal Working conditions Ambient temperature: -20 -60 ° C Humidity: 5 --95% RH Power supply voltage: 80 - 264 V AC or 24 V ± 4.8 V DC fluid conductivity: 20mS / cm or more
