Sifam Tinsleys Sigma Series LML Meter
The Watt and Var meters, LML 96 are offered for
- single phase,
- 3 phase balanced load 3 or 4 wire,
- 3 phase unbalanced load 3 or 4 wire AC Systems
These instruments are suitable to indicate forward (export / out going) and reverse (import/in coming) power flow as well as inductive and capacitive reactive power. They can be used both on sinusoidal and non-sinusoidal currentThese meters offer several advantages in Switchboard & Generating Set panels. Number of meters can be mounted in a Panel Cut out (Mosaic Mounting). The Bezel, Front window glass and Dial can be easily replaced.

SiFM Series (Pointer Frequency Meter)
The pointer type frequency meters, FM 48/ 72 / 96 / 144 housed in-molded polycarbonate cases are suitable for the measurement of frequencies in the range of 45 to 450 Hz.
For maximum accuracy, the essential measuring range is obtained by suppressing the unwanted frequency span. These instruments offer several advantages in switchboard and Generating Set Panels. The number of meters can be mounted in a Panel Cut out (Mosaic mounting). Front glass, Bezel & Dial can be easily replaced.
SiFM Series Analog Frequency Meter.
The pointer type frequency meters, FM 48/ 72 / 96 / 144 housed in-molded polycarbonate cases are suitable for the measurement of frequencies in the range of 45 to 450 Hz.
For maximum accuracy, the essential measuring range is obtained by suppressing the unwanted frequency span. These instruments offer several advantages in switchboard and Generating Set Panels. The number of meters can be mounted in a Panel Cut out (Mosaic mounting). Front glass, Bezel & Dial can be easily replaced.
Sifam Tinsley Power Factor Meter
The moving coil indicators and a phase angle adjuster are used to monitor changing power factor conditions on irreversible balanced load systems.
The power factor is indirectly determined by measuring the phase angle φbetween current and voltage (both sinusoidal). However, the indicators are calibrated in values of the cosine of the angle φ. These meters offer several advantages in Switchboard & Generating Set panels. The number of meters can be mounted in Panel Cut out (Mosaic Mounting). The Bezel, glass, and dial can be easily replaced.
SiDE (Moving Iron AC Meter)
The moving iron panel meters, DE 48/72/96/144 housed in moulded polycarbonate cases are suitable for the measurement of AC currents for frequency range of 15…400Hz and voltages in the frequency range of 15…100Hz.
Moving iron meters indicate rms-values practically independent of waveform even of high harmonics. Error of indication may occur for extreme waveforms (e.g. phase gating controls) & for frequencies above 100KHz.
These meters offer several advantages in switchboards and Generating Set Panels. Number of meters can be mounted in a Panel cut out Mosaic mounting). For CT operated ammeters, dials can be fitted based on CT ratio. Glass and bezel can be easily replaced.
SiDS (Moving Coil DC Meter)
The moving coil panel meters, DS 48/72/96/144 housed in moulded polycarbonate cases are suitable for the measurement of DC currents and voltages.
These instruments offer several advantages in switchboards and Generating Set Panels. Number of meters can be mounted in a Panel Cut out (Mosaic mounting). Front glass, Bezel & Dial can be easily replaced.
