BATCH CONTROLLERS / FLOW INDICATORS � Predefined / Universal type MODEL 855

( Microprocessor based & Fully Configurable )




Pantech Instrument’s Model 855V represents BATCH CONTROLLERS / FLOW INDICATORS AND TOTALIZRS for flow applications where single flow signal is available. Model 855 is an ideal instrument for controlling amount of material flow in every batch. The input signal can be a current/voltage/linear signal from a flow transmitter or pulses from turbine meters. It can also be UNIVERSAL input type, where user is allowed to select and configure the input signal. The analogue signal is square rooted if required, and similarly for digital pulses Litre/Pulses ratio ( i.e. K factor )can be adjusted to achieve precise measurement of flow and hence batching.


The desired counts or the BATCH VALUE(S) are set through push button switches given in front of instrument. The relay(s) is/are energised to start the flow and batch counter starts. When set batch counts are reached, relay(s) get de energised as per the batch-relay settings and the flow is stopped. The cycle repeats when start button is pressed again. The flow can be interrupted during the working cycle by pressing stop button and again started by pressing start.


Optionally the instrument is designed to give a RETRANSMISSION ISOLATED signal on INSTANTANEOUS FLOW RATE. Serial communication outputs for computer system interfaces are also given optionally. The user is allowed to feed in : FLOW RANGE ( for linear inputs ), K FACTOR ( for pulse input ), COUNTS/Hr., FLOW TYPE and all other related parameters by front four keys only. 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 855V at a glance :

  1. Is to be used specifically for BATCHING purpose only. However the instrument also indicates instantaneous flow rate and totalizer in normal run.

  2. Accepts a linear signal or pulse type signal. Can also work in UNIVERSAL input mode, where the user selects and configures the input type by front keys only.

  3. Allows the user to set maximum 2 nos. of BATCH VALUES. Each batch value to activate 1/2/3/more relay(s).

  4. BATCH VALUES can be set in values or percentages.

  5. Batching process can be shown in INCREMENT or DECREMENT modes as selected by the user.

  6. All the configurations calibrations etc to be done by front keys only.

  7. All batching related functions to be done by front keys only.

  8. Enclosures of all types – WP, FLP, IP-65 grade etc. available.

Pre-requisite from the USER:

  1. What is the Input signal type if he chooses to go with PREDEFINED INPUT type model

  2. What is the flow range with linear inputs. What is the K factor with Pulse inputs ( configurable )

  3. Flow type to be interpreted – Linear or square root ( configurable )

  4. Enclosure type / Safety standards etc.
