Mass Flow Meter Filling System: Integrated Industrial Fluid Batch Skids
Quick Answer: Silver Automation Instruments supplies mass flow meter filling systems and integrated industrial fluid batch skids for chemicals, food oil, paints, solvents, LPG, and water based batches. The standard skid includes a Coriolis mass flow meter, a fast shutoff valve, a local batch controller, and piping on a steel frame. Send us your fluid type, viscosity in cP, flow range in kg/h, pressure in bar, temperature in °C, and pipe size in DN for a full quotation.
What Is an Integrated Mass Flow Meter Filling Skid
A batch skid is a preassembled frame that carries the meter, valve, controller, and often a pump. The operator enters a target weight or volume. The controller opens the valve, the Coriolis meter reads mass flow directly, and the controller closes the valve in stages to avoid overshoot. Because the meter measures mass and density, the system does not need separate temperature compensation for most liquid batching. A paint plant in Vietnam uses this method to fill 20 kg pails and 200 kg drums on the same line. They switch the target value on the HMI and the same DN25 meter handles both packages.
Why Coriolis Meters Work for Batch Filling
Here is the thing. A volumetric meter reads volume first. Then it needs density and temperature corrections to get weight. That adds error. A Coriolis meter also reads density in real time. Most Silver Instruments Coriolis models hold ±0.1% mass flow accuracy for liquids and ±0.5% for gas. For batching, the totalized mass accuracy often sits near ±0.2% or better when the valve control is tuned. That is the key number for a filling system. You sell by weight, so you should measure by weight.
Typical Skid Layout and Main Components
A standard skid from Silver Automation Instruments includes a DN10 to DN100 Coriolis mass flow meter, a pneumatic or solenoid shutoff valve, a batch controller or PLC, a power supply, and a local pushbutton station. Larger skids add a pump, a filter, a pressure transmitter, and a return line. The frame is welded carbon steel with epoxy paint or 304 stainless steel for food and chemical duty. Electrical panels are IP54 or IP65. For hazardous areas, we supply ATEX Zone 1 or Zone 2 certified meters and valves. The piping can be 316L stainless steel, PTFE lined, or carbon steel depending on fluid.
Batch Accuracy and Speed Numbers That Matter
We have seen a coconut oil producer in the Philippines fill 180 kg drums with ±0.15 kg repeatability using a DN25 Coriolis meter. A solvent distributor in the UAE runs 1,000 kg IBC fills with a DN40 skid and holds ±0.5 kg total error. Fill speed depends on valve sizing and pipe pressure. A DN15 meter with a 1 bar to 3 bar supply may fill a 20 kg pail in 18 to 25 seconds. A DN50 skid at 6 bar can move 150 to 200 kg/min during the fast fill stage. The controller then slows the valve for the last 2 to 5 percent of target to prevent overshoot. That two stage valve control is what separates a repeatable batch skid from a basic manual line.
Fluid Types We See in Southeast Asia, Oceania, Middle East and Africa
The same Coriolis skid platform handles many fluids because mass flow measurement is not limited by viscosity or density. We have quoted systems for palm oil in Indonesia, molasses in Thailand, printing ink in Australia, liquid soap in Kenya, edible oil in Mexico, and diesel additives in Saudi Arabia. For food grade batches, the wetted parts can be 316L stainless steel with Ra 0.8 µm surface finish. For solvents and LPG
Recommended Models for Batch Filling
For small packages from 0.5 kg to 50 kg, we recommend a DN10 or DN15 Coriolis meter. The common model is the SL-CMF series with 4-20 mA HART, pulse output, and RS485 Modbus RTU. For pails and drums from 20 kg to 300 kg, a DN25 or DN40 meter works well. For IBC and bulk tanks from 500 kg to 5,000 kg, we use a DN50 or DN80 meter. If your fluid has entrained gas, a bigger flow tube or a back pressure valve helps keep the meter stable. If you need high speed filling, we pair the meter with a fast pneumatic ball valve or a two stage valve assembly. The controller can store 100 or more recipes. Each recipe includes target weight, fast flow cutoff, slow flow cutoff, and preact value.
How to Specify a Skid Without Overpaying
Most engineers skip this part. They send a datasheet with only flow range and pressure. That is not enough for a stable batch skid. We also need fluid type, viscosity in cP, density in kg/m3, filling volume, required accuracy, filling time, pipe size, hazardous area classification, and power supply. For example, a water like fluid at 1 cP in a DN25 meter can batch 10 kg in 8 seconds. The same meter with a 10,000 cP polymer may need 30 seconds and a wider valve. If you do not know viscosity, send us a sample value or a similar product. We can select the meter bore and valve size from our test data. In practice, a small oversizing adds cost without improving accuracy. A small undersizing slows your line and can make the pump cycle too often.
Frequently Asked Questions
What batch accuracy can a DN25 Coriolis skid hold during drum filling?
A DN25 Coriolis meter with two stage valve control typically holds ±0.1 kg to ±0.2 kg on a 180 kg drum fill. Repeatability depends on valve speed, back pressure, and fluid viscosity.
Can the skid handle viscous fluids like syrup, paint, or molasses?
Yes. Mass flow meters do not need Reynolds number compensation like turbine meters. We size the meter bore and valve for pressure drop. High viscosity fluids above 5,000 cP use a larger meter or a wider flow path.
What is the smallest filling volume for a DN15 Coriolis meter?
A DN15 Coriolis meter can handle fill volumes from 0.5 kg up to 50 kg. Below 0.5 kg, a specialized micro flow Coriolis or a syringe style filler may be needed.
Do you supply ATEX Zone 1 versions for solvent or LPG filling?
Yes. We supply ATEX Zone 1 and Zone 2 certified Coriolis meters, valves, and control panels for solvent, LPG, and alcohol filling. The certification covers Ex d and Ex ia protection depending on the site.
What details do you need to quote a mass flow meter filling skid?
We need fluid type, viscosity in cP, density in kg/m3, filling volume, required fill time, target accuracy, pipe size, pressure, temperature, hazardous area class, and country of installation.
