HCG Hydrostatic Tank Contents Gauge
HCG Hydrostatic Tank Contents Gauge
The HCG series self-powered hydrostatic tank contents gauge requires no external power source for operation and gives a continuous readout of the contents within a tank without the aid of batteries or hand pumps.
Self-powered tank contents gauges are economic and simple to install
HCG tank contents gauges are constructed with 316 stainless steel diaphragm, stainless steel or mild steel diaphragm sensor housing, a PVC sheathed copper micro bore pressure capillary and stainless-steel indicator gauge.
Displacement of the diaphragm due to applied hydrostatic pressure is transferred via an inert gas filled capillary to the remotely positioned indicator. Each indicator is individually scaled and calibrated in customer requested units according to individual tank dimensions.
The capillary external to tank is heavy duty seamless copper mechanically protected by a fire-retardant PVC sheathing compound, and can be supplied to a maximum of 20 meters in length. For internal to tank mounted sensors the capillary is sheathed in a protective stainless braided oversheath.
Design simplicity is a key feature that reduces time and cost for installation. Each unit is supplied with the required calibration and scale markings and requires no commissioning on-site.
A full range of sensor connection options are available including flanged, threaded running-nut and submersible designs. These can be connected directly to standard / existing tank fittings and can even be fitted to full tanks by means of non-return or isolating valves.
The indicator gauge can be positioned at any height above or below the sensor datum level point.
These holding tank gauges are maintenance free and require no routine calibration.
