Level gauges Turbo Flow LVG (autonomous, with built-in data transmission unit)
Our dealersPurpose:
Level gauges are used for:
- measurement of level of various liquid products;
- levels of separation of immiscible liquids;
- temperature and pressure of monitored medium;
- calculation of monitored medium's volume and weight;
automatic data transmission to the dispatching station.
Field of application:
-
gas industry;
-
chemical industry;
-
oil refining;
-
other industries with tank farms.
The instrument can be installed in remote places with absence of permanent power supply, while allowing for monitoring of its operability and the measured parameters.
Features:
The feature of this modification is the possibility of making a fully autonomous instrument with the function of data transmission to the dispatching station.
Instrument functions:
- Measurement of liquid product level;
- Measurement of media separation level;
- Measurement of temperature of monitored medium;
- Indication of layer-by-layer temperature of monitored medium;
- Pressure measurement;
- Calculating the weight of monitored medium;
- Calculating the tank volume;
- Calculating the degree of tank filling;
- Exchange with automatic process control systems (APCS) via GPRS channel.
The instrument can be equipped with a density meter for full determination of all parameters of monitored medium.
