YOUR STORE FOR LOAD CELLS, SCALE, WEIGHT INDICATORS.

One recipe, up to 11 ingredients, one controller.

WT-MIFill doses liquids and bulk material by weight, one ingredient after another, into the same vessel. MIFill Studio lets you manage the products, recipes and users from a PC on the network. It runs on the WeightechUSA WT8000 controller and is programmed and supported by WeightechUSA in Davie, FL.

Where it fits

WT-MIFill fits wherever several ingredients go into one weighed vessel, one after another: a mixing tank on load cells, a blending hopper, or a drum, tote or IBC on a platform scale. Automatic ingredients are dosed through their own valves or feeders; ingredients added by hand are weighed in the same batch.

Typical uses

  • Liquid blends and syrups in a mixing tank
  • Coatings, resins and adhesives by recipe
  • Cleaning and chemical products
  • Dry premixes into a weigh hopper
  • Drum, tote and IBC batching on a floor scale
Process schematic. Two liquid ingredients from storage and one bulk ingredient from a hopper are dosed into one mixing vessel through valves or a feeder, with a hand-add port for a manual ingredient. The vessel stands on load cells wired through a junction box to the WT8000 controller running WT-MIFill. The controller switches each fill valve, with fast and slow outputs for two-speed dosing, and the discharge valve, which sends the batch to a downstream pump or holding tank. A label printer, a PLC over fieldbus and a PC running MIFill Studio over the network connect to the controller.

How a batch runs

Six steps from login to label. The terminal alongside follows as you scroll, one real screen after another.

  1. 1

    Log in

    The operator enters a user ID and password. Only stored users can start a batch.

    Terminal login screen: select the user
    Terminal login screen: user ID and password entered
  2. 2

    Pick the recipe

    Recipe ID, lot number and, if enabled, the number of fillings.

    Terminal recipe selection screen
  3. 3

    Dose each ingredient

    The terminal tares, opens the fast output, switches to slow near the target and closes at the cut-off point. The free fall is corrected automatically for the next batch.

    Terminal during an automatic ingredient, fast output on, weight rising
  4. 4

    Add manual ingredients

    For hand-added ingredients the terminal shows the target and waits for the operator to confirm.

    Terminal after the manual ingredient is confirmed
  5. 5

    Check and move on

    Each ingredient is checked against its tolerance, then the next one starts on top of the same container total.

    Discharge and print

    The vessel discharges, the batch label prints and the record is stored.

What the controller does

Recipes
200 recipes, 99 products, 20 users, up to 11 ingredients per recipe.
Automatic and manual
Automatic and manual ingredients in the same batch.
Two-speed dosing
Coarse/fine dosing with automatic free-fall correction.
Checks
Tolerance check and flow-rate monitoring set per product.
Output ports
Each ingredient gets its own output, assigned automatically or set per ingredient in the recipe (OUT2 to OUT15). The terminal warns at recipe selection if two ingredients share a port or a port is out of range.
Printing
Batch label and statistics ticket on a 4 x 6 in label printer.
Records
Batch records to a CSV file, copied to USB or fetched over FTP.
Languages
Operator screens in English, Spanish, German and French.
Filling mode
The same terminal also fills a single product to a target weight.

MIFill Studio

Edit products, recipes and users on a PC instead of the terminal keypad. Changes go to the unit over the network and are in use from the next batch.

  4. Errors are caught on the PCValues the unit cannot hold are marked red and block the send.

Your edits do not overwrite values the unit learned on its own, such as a corrected free fall.

PLC and fieldbus

A PLC can run the batch. It reads the weights, the process state and the error codes, and sends the commands listed here.

The data words are the same on Modbus TCP, Profibus DP and EtherNet/IP (EtherNet/IP needs the terminal's ETX module). The terminal monitors a heartbeat, so it detects a lost PLC link.

Operator login, lot number and number of fillings stay at the terminal.

The PLC sends
