Clark Solutions EX101-S 电磁流量计

"The complete lack of moving parts of this insertion flow sensor is the source of its reliability. There is no rotor to stop turning in dirty water and there are no bearings to wear out. A rapidly reversing magnetic field is produced in the lower housing, and as the fluid moves through this field a voltage is generated. This tiny voltage is measured and translated into a frequency signal which is proportional to flow rate. This square wave signal can be sent directly to a PLC or other control, or can be converted using any of the associated family of indicators and converters.","A modular system of electronics can be attached directly to the flow sensor or remotely mounted. The FT420 provides full indication of rate and total, plus 4- 20 mA output. The AO55 provides a 4-20 mA output, and the FS30 can be used as a precise setpoint flow switch.","The installation fitting of the EX sensor is standard male NPT, and can be directly threaded into ordinary saddles or threaded weld fittings. The EX115 and 215 include an isolation valve, allowing hot-tap installation or installation and removal under pressure. The standard isolation valve is Bronze, but a 316 Stainless Steel valve is available as an option if needed."
