Trodeks Instruments, TFCIV Series Variable Area Float Flowmeters are low cost flowmeters designed to measure the instant flow of gases such as air or nitrogen, as well as water or water-like properties. Light and durable with complete plastic design. TFCIV Series variable area float Dammeters with connections or threads can be connected to the installation in a very short time. In particular, HCl or NaOH scales are available for Treatment Systems. There is no guide bar in which the buoy flies. This prevents possible clogging or clogging. In plastic products, resistance temperature and resistance pressure are inversely proportional. Please consult during product selection.
