FT 200 series flow meters are extremely versatile flow meters that can be used for a wide variety of applications. These meters offer extreme reliability and low cost for flow measurement. FT 200 series flow meters can be used for water and water like liquids. These meters can also be used for line sizes from 0.5” to 48”. Microprocessor based instrumentation ensures accurate readings for both rate of flow indication and total flow indication. A number of programmable features including In-line calibration are standard. Advanced models can offer relay outputs for signals exceeding rate of flow or total flow set points. Industry standard 4-20mA output is optionally available. These instruments are field programmable and doesn't needs any special instruments for calibration. All variables and program parameters are programmable through key pad provided in the instrument. In addition, these meters have RS485 or RS232 Mode of communication to PC through MODBUS Protocol. All the parameters are saved in a non volatile EEPROM memory which doesn't needs any external battery. There is a advanced power fail feature by which even if there is any power failure the Total Flow reading is automatically saved to memory and resumes with the same value after Power On FT200 is available in a IP65 enclosure with field mount, panel mount, pipe mount as well as wall mount options.

Suitable for different types of fluids.Type of connection : Screwed or Flanged. Material of construction: C.I., C.S.,SS-316, SS-304 or any other depending upon application.Available Sizes : 6 NB to 250 NB

Pantech Instrument’s Model 845V represents FLOW INDICATORS TOTALIZERS CONTROLLERS for flow applications where single flow signal is available. Based on the flow application and the type of flow data signal, hence this model can be used in VOLUMETRIC and MASS flow measurements, both. The instrument accepts any predefined linear type of signal, and converts it into INSTANTANEOUS FLOW RATE to a resolution of 44.5 digits. TOTALIZED value is displayed through 8 digits red LED and this totalizer value is always protected against power failures through internal memory structures of microprocessor. Optionally the instrument is designed to give two contact relay outputs and a RETRANSMISSION ISOLATED signal on INSTANTANEOUS FLOW RATE. Serial communication outputs for computer system interfaces are also given optionally. All configurations, calibrations and output fine tunings etc. can be performed by front four keys only without opening the instrument. In the core of all the functions lies the latest and highly proven microprocessor based chipsets. The high end softwares ensure the most user friendly interactions by the user. 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 operations. Model 845V : Is to be used when a single flow signal input is there. Application can be a VOLUMETRIC MASS type, depending upon the system design and type of flow transmitter signal output.

Full view Sight Flow Indicator is recommended where maximum visibility is desired on low pressure applications ( Upto 8 kg/cm2). It can be used in vertical or horizontal lines with a negligible pressure drop. It is ideal for visual check of the presence, colour & condition of liquid, where there is intermittent flow, partially filled lines or entrained air. This Sight Flow Indicator is rugged in construction, comprises of havi walled buttress borosilicate glass cylinder placed between two flanges. Teflon gaskets offer superior protection & better sealing. Available in all types of flanged & threaded process connections. Various material of flanges and linings is available as per applications requirement.     Features : * Blow hole free investment casting body.  * Electo polish finish for better registance to sarface corrosion.
