KH / LZ- metal rotameter for small caliber and low velocity medium flow measurement; reliable, low maintenance, long life; do not ask for a straight pipe; wide flow ratio of 10: 1; two-line large LCD Optional on-site instantaneous / accumulated flow display, backlit uniaxial sensitive indicator; non-contact magnetic coupling drive; all-metal construction, metal rotameter suitable for high temperature, high pressure and corrosive media; can be used for flammable, explosive hazardous locations; optional wire, battery, AC power supply; multi-parameter calibration function;. with data recovery, data backup and power-down protection professional production of SZFZ series of metal flowmeter has a simple structure, reliable operation, the scope Canton, measurement accuracy, ease of installation and so on. Details KH / LZ- metal tube rotameter: high temperature, high pressure, SZFZ series flowmeter common type of metal and non-corrosive, more than two types of instructions are divided into the field type (SZFZZ-) and electricity Remote type (SZFZD-), ordinary type flow sensor, instrumentation materials (1Cr18Ni9Ti), anti-corrosion for (1Cr18Ni9Ti) lined PTEF. If KH / LZ- metal tube variable area flowmeter medium containing ferromagnetic particles, magnetic filter should be installed at the entrance of the flowmeter. It should be the same material in the corresponding meter.
