Designed for low flowrates, the model T flowmeter is a precision instrument embodying the inherent simplicity, versatility and economy of the classical variable area meter. It is particularly suitable for metering carrier gases in chromatography, indicating and controlling gases in manufacturing processes, liquid and gas measurement in laboratories, pilot plants, flow and level indicating.
Shipped completely assembled, flowmeters include standard mounting fittings in a choice of materials, side plates, thick protective magnifying front shield and back plate, optional built-in control valve, and flowtubes selected from the Flow Capacities tables. Panel mounting style is convertible to bench mounting through the use of the optional acrylic tripod. The tripod has a built-in spirit leveler and leveling screws.
Flow tubes for these meters are available with two types of scales, suitable for different types of applications.
Meters are available with built-in needle valves (CVT™ ), high precision metering valves (HRT™) with “non-rising stems”, or with no valves. The higher cost of HRT™ valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flowrates.
