Mechanical storage tank level indicator
|
| |
This is a purely mechanical arrangement to show the level of liquid in the storage tank. There are mechanical linkages involved in measuring and indicating the level on the face of the tank in terms of percentage of tank volumetric capacity. Large and easy to read dials are also convenient to replace. Material of construction is compatible to all most all the liquids. Gauges can work in pressurised liquids up to 30 bar. |

Reed-switch type for storage tank level
|
| |
There are series of reed switches and fixed solid state resistance mounted on a linear PCB. The magnet on float activates reed switch that brings in circuit a set of resistance calibrated in 4-20 mA range. This gives a read out. The controller can be calibrated to give out signals / relay outputs to operate / close other equipment. This may have a linear accuracy of 3 -5 mm. |

4-20 mA probe for storage tank level measurement
|
| |
This level probe works on the Magnetostrictive principle. As the magnetic signal generated from the transmitter is reflected by the magnet in the float the electronic head measures the time lag and speed of the signal to derive exact level. The probes are accurate and have an excellent repeat accuracy. The probe can be used for variety of fluids of different chemical composition and density. Probe remaining the same only float changes for various liquid applications. |

Magnetostrictive probe for storage tank level
|
| |
The controller is a comprehensive tank gauging and leak detection system that can simultaneously monitor product level, water level, temperature and leaks for up to 8 tanks. The controller can also take 44 BrightEye sensors for differentiating liquids or detecting their presence. Built-in microprocessor gives each sensor an ability to identify itself and its location. Level, alarms, logs can be displayed on its 4 line backlit LCD display. Its communication ready for remote. |

RS485 compatible probe for storage tank level
|
| |
The probe utilises Magnetostrictive technology that provides users the same level of reliability, durability and cost-effectiveness. MTG Probe used with the controller monitors product levels and temperature for aboveground or underground storage application. Through controller probe monitors high level, low level, presence of specific liquid and generate alarm or relay signal to initiate down stream operation. |

Ultrasonic probe for storage tank level
|
| |
The probe can measure level up to 25 M with digital communication of the data. It can generate a power relay output and alarm for remote operation. The probe can be used for full temperature compensated volume for liquids with distinct surface. It has data logging facility to retain data up to 7 days after power failure. It can store up to 10,000 sets of data triggered by specific events. The probe can communicate through infrared for data logging. |

Capacitance type probe for storage tank level
|
| |
Capacitance type probe takes reference when the tank is empty that acts as one of the electrodes with the probe acting as the other. The liquid filled act as a dielectric and change in capacitance is registered due to change in the level of liquid. |

High level alarm switch
|
| |
This is a top mounted magnetic level switch for monitoring a predefined level. E.g. LPG storage tank is allowed to store 85% of its volume capacity that has to be monitored externally and generate a signal to cut off filling of liquid in the storage tank. For initiating such actions at different 4 levels there can be up to 4 floats on the probe. |

Specific level control switch
|
| |
There can be a series of switches that can initiate action at predetermined level of liquids. Such levels have to be determined before installation of the level switch and as such to be adjusted on the probe before hand. |

Side mounted level control switch
|
| |
These magnetic level switches are mounted on above ground storage tanks. The provision for mounting is already considered at design stage. The magnetic switch is actuated by a magnet moved by float at end of a lever. There can be more than one change over that can operate at the same level. |
