POLY PHASE | SINGLE PHASE

ELECTROMECHANICAL METERS - Single Phase Electromechanical Watthour Meter

TYPE F-72 FAMILY OF METERS

Single phase induction Watt-hour meter, Model F-72 family of meters. They are accuracy class 2.0 meters for single phase 2 wire or single phase 3 wire balanced circuit use, having cyclometer type register, magnetic suspension bearings and anti-reverse device (if required).

The F-72 family of meters is available in both 50 and 60 Hz designs, 120 or 240 volts and in maximum current ratings of 40, 60 and 100 amps.

Beside maintaining a very high standard of workmanship during manufacture of these meters Syed Bhais have developed strict quality control procedures based on internationally accepted methods, to ensure production meeting the customer's specifications and relevant IEC, BS or ANSI standards.

Features

	Magnetic suspension bearing ensure friction free rotation with minimum of filt error.
	Die Cast construction of the braking magnets ensures stability of calibration throughout entire meter service life.
	Twin bobbin coil design ensures improved dielectric strength and low watt losses.
	Specially trated current coil improves over load performance of the meter.
	The meter performs satisfactorily for years and years at light loads because of low friction in register and bearing
	assemblies.
	Our F-72 family of meters has successfully completed all the type tests at National and International independent
	Laboratories Pakistan as per IEC specifications.

Avoid Lost Revenues & Keep Expenses Down With Advanced, Long-Life F-72 Family Of Meters

	Magnetic Suspension
	Precise calibration and high Accuracy
	Corrosion Resistance Construction
	Fully Sealed and weather- Proof design
	Extended Load range
	Longer term calibration Stability
	Tamper resistant meter Cover

Meter Frame

All functional components of F-72 family of meter are fastened to a die-cast aluminum frame in a manner to assure long lasting mechanical stability that will add years to the life of your meter. Broke Magnets including temperature compensation are cost into the frame for providing long term stability. A feature unique to F-72 family of meters.

Meter Cover & Meter Base

F-72 family of meter can be supplied with either a tampered high resistant glass or a polycarbonate cover. Both provides full visibility and superior protection against tampering or damage. Rigid base made of aluminum silicon die - cast alloy, designed for optimal deformation and corrosion resistance. Molded phenolic base is also available on request.

Potential And Current Cores

Mounted on templates and riveted in order to assure perfect alignment and rigidity of the assembly and coated with electrophoretic paint against oxidation.

Potential Coils

Potential coils are encapsulated in Nylon; resulting in a coil which is completely moistureproof and well protected against high voltage surges. The design of potential coil is in two parts to reduce voltage stress and increase life under extreme service conditions. Resulting for a wattless of less than 0.8W.

Current Coils

The current coil wound from large cross-section copper strip and heavily insulated by special epoxy resin ensures its high overload capacity. Laminated cores making the potential and current stators are specially electrocoated to resist corrosion. According to the type of application, current coils can be supplied for max. currents of 20, 30, 40, 60 or 100 amp.
