Designed for low flowrates, the model P 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, etc. 150 mm Meter with CV™ Valve. Shipped completely assembled, flow meters 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 flow tubes selected from the Flow Capacities tables.
Flow tubes for these meters are available with two types of scales (direct reading or millimeter scale), suitable for different types of applications.
Meters are available with built-in needle valves (CV), high precision metering valves (MFV) with “non-rising stems”, or without valves. The higher cost of MFV valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flow rates.
