Flow Star series LCT-01 are capacitance type level transmitters. The probe is based on properties of capacitor. Vessel wall & probe forms two electrodes. If vessel is of non conductive material, the probe will be double rod type. The distance between electrode & surface area of electrodes remain unchanged. The variable is the depth of the material being measured which represents the dielectric constant between two electrodes. Air & Vacuum have relative dielectric constant as 1 & that of liquids , it is greater than 1. The capacitance of the capacitor therefore depends on how much material lies between the probe & vessel wall i.e. whether the probe is covered with or free from material. The capacitor changes with change in level of the material & provides corresponding 4-20 mA DC continuos output.

COATING :

• Coating over sensing probe is very common
• Flow star engineering sensors ignores any accumulation and coating, avoid false signals.
• Liquid like tarcaol, chrome, poly Oil etc. are very sticky and accumulate over the sensing probe. Our instrument does not effect on such type of accumulation.

TEMPERATURE :

Temperature in process material can goes upto 1000deg.C. or more for certain applications. Flow star engineering provides suitable sensors for high temperature or ambient conditions.

PRESSURE :

• Inside the vessels/tank pressure is generated for fluidizing of process materials. Under such conditions the sensor has too be selected as per pressure conditions. Flow star engineering provide suitable sensor.
• For acid/ alkali application we provide PTFE/Teflon insulation on the sensing probe to avoid Erosion and these perform without any troubles.

SYSTEM DESCRIPTION:

Model FERF-200 has two parts: one is sensing probe and another is called electronic Unit. Both are connected by our coaxial cable. The sensing probe has two parts active and shield section, both insulated from each other.
Model FERF-200 works on Radio frequency principle. Oscillators generate a very low power radio frequency signals, which is equal in frequency phase and amplitude, provided to shield and active sections of the sensing probe and reference signal is taken from the ground of the electronic housing installed the nearest structure. The signals provided to the shield parts remain constant by use of a compensating circuit. The signal to the active section is not compensated i.e. it can vary. Inside empty vessel gas or suspended dust particles always present. The Signal propagation continue towards zero (vessels body). We call it free propagation inside the empty hopper, there will no change in signals. When material stars filling and goes up to the sensor and submersed some length of active part of the sensor by the material, The signal propagation still continues, but this time signal passes through the difference media, and signal will try to exhort more energy since same signal was passing earlier freely while hopper was empty & now the signal become weak in comparison to the shield. The variations in active signals are compared with the shield signal and actuates relay by the predetermined set value with the reference of ground. We take a potential free relay change over contact for further automation/control.
