01
Product scope
Liquid-filled gauges in 40–100 mm dial sizes, accuracy 1.6 % or 2.5 %, glycerin (standard) or silicone oil fill (for low-temperature applications). Phosphor-bronze Bourdon tube, stainless steel or brass connector. Bottom or back connection.
02
Why liquid-filling works
The glycerin or silicone fill damps needle oscillation caused by pump vibration, compressor pulsation or hydraulic pressure spikes, making readings clear and protecting the movement from fatigue. Fill choice should be reviewed by temperature and medium compatibility.
03
Typical applications
Pump and compressor discharge lines, hydraulic power units, reciprocating engine manifolds, HVAC water systems, irrigation skids and any service with continuous vibration or fluctuating pressure.
