Pantech Instruments, an eminent manufacturer of process control instruments since last 15 years, has developed this type of meter by their indigenous R&D efforts. The flow meter is definitely a state of technology product, totally in line with all the industrial and gas standards.
Principle of Operation
The thermal sensor uses the principle of heat dissipation. A heated sensor is inserted into the stream of gas flow. The cooling effect of the gas is measured, transduced and interpreted as flow. The cooling effect is a direct function of the heat transfer that takes place due to the flow of gas. The heat transfer in turn is a direct function of the velocity as well as density of the process gas. Hence variations in temperature and pressure in the process gas are automatically compensated. For all practical purposes the output signal obtained is pressure and temperature compensated “massflow” signal. Thus the compensated flow independent of pressure and temperature variation is indicated without need for any separate transducers for the same.
The user friendly features and main advantages of this flow meter are :
In areas of flow metering, where the process gas pressures are very low, conventional flow metering techniques present a no. of limitations. In case of Thermal Mass Flow meter, upstream pressure required is very low because pressure drop across the sensor is negligible. Hence it works in place where OrificeRotameter type flow meters have failed. For this reason it is ideally suitable for very low height gravity feeds, reflux lines, condensersaccumulator systems etc.
There are no moving parts in the system. So choking, jamming effect are not observed even after very long run of the meter. There is no need to carry out periodic cleaning unless the fluid is very viscous or dirty.

However the RPM value is auto calculated, but this programmed range can set the value of retransmission signals which can be optionally taken from the instrument. Further it can be designed to generate maximum of 4 nos. of potential free contacts. All the configurations like : PPR, setpoints, alarm types, ZERO and SPAN for retransmission etc. can be done with the help of front keys only . It is also facilitated with internal transmitter power supply of 1224 V DC, to power up proximity sensors.
The instruments are available in panel mounting as well as wall mounting versions. All models can be operated on 24V DC, 230V AC and 110V AC power supplies. Power supply is isolated from rest of the circuit.
The instrument incorporates low drift operational amplifiers and industrial grade components for long trouble free operation. Burn in of each module ensures long trouble free operation.

Alarm annunciator microprocessor based model 885
introduction
pantech's alarm annunciator, series 885, is an ideal instrument for indicating field fault conditions in the control room.
It is designed to sense nonc potential free contacts for all the channels in a simultaneous mode. The high end microprocessor chips assures the response time in microseconds while sensing all the channels in round robin fashion. The audio and visual output is provided in the unit for alerting plant personnel when fault condition occurs. Controlling keys acknowledge, reset and test are provided on the front of the instrument. For remote controlling of the unit, same keys can be provided on the back plate. Pattern of rows and columns change with change in total channels.
features of model 885 :
response time is very fast. Pertaining to high end microprocessor chipsets on board.
first fault feature availed.
features like manualauto reset, ring back, first up are provided as optional.
any no. Of channels windows possible ( for more then 36 nos. Check with factory ends )
enclosure mountings dimensions etc can be customised as per the user requirements.
weatherproof, flame proof, ip65 grade – all type of enclosures available.

MODEL 836 - SQUARE ROOT EXTRACTORS
Introduction
Pantech's Square Root Extractor Module, model 836 is designed to provide linear output for the non-linear flow equivalent type signal. It provides an output of 4 – 20 mA DC capable of driving a load of upto 800. The input-output relationship can be defined as OUTPUT = SQUARE ROOT OF INPUT.
The module accepts 4 – 20 mA DC signal from two wire and non two wire transmitters. The module also accepts 1 – 5 V DC signals. Output is a square root of the input. The instrument has a facility of TPS 24 V DC to power up two wire transmitters. In general version, the instrument is available in DIN RAIL version.
The module is also available in Euro card format of 3U height and alternatively in a wall mounted housing. 20 Euro card modules can be housed in a 19” Euro card cage. The Euro card modules can be powered from 24V DC power supply whereas wall mounted modules can be powered from 110V AC or 230V AC too. Power supply is isolated from rest of the electronics.The modules incorporate low drift operational amplifiers and industrial grade components. Burn in of each module ensures long trouble free operation.
Rugged & Time Proven Designs
Three Port Isolation – Opto and Galvanic
Predefined input, output & ranges
Transmitter P.S. @ 24 V DC.
