Flow Totalizers
Product Overview
A Flow Totalizer is an industrial instrument used to measure, display, and record the total quantity of fluid (liquid, gas, or steam) that has passed through a pipeline over a specified period. It works together with flow measurement devices such as flow meters and transmitters to integrate the flow rate over time and calculate cumulative volume or mass.
Flow totalizers are commonly used in process industries where accurate monitoring of consumption, batching, and custody transfer is required.

How it works (simple explanation)
A flow meter installed in the pipeline measures the instantaneous flow rate (e.g., liters per minute or kg per hour).
The flow totalizer:
- Receives the flow signal (pulse, 4–20 mA, or digital signal).
- Converts the signal into engineering units.
- Continuously integrates (adds up) the flow rate over time.
- Displays the accumulated total flow (e.g., total liters, cubic meters, or kilograms).
In simple terms:
- Flow rate tells you how fast fluid is moving.
- Flow totalizer tells you how much fluid has passed in total.
What it measures
- Total Volume (L, m³, gallons)
- Total Mass (kg, tons, lb)
- Batch Quantity
- Daily / Monthly Consumption
- Instantaneous Flow Rate (optional display)
Key advantages

Installation
Installation Guidelines:
- Mount in control panel or field enclosure.
- Connect input signal from flow transmitter (pulse or 4–20 mA).
- Provide stable power supply (typically 24 VDC or 220 VAC).
- Configure scaling parameters (flow range and units).
- Set reset, alarm, or batch parameters if required.
- Connect communication lines (Modbus/RS485) if used.
Important:
Proper grounding and shielding of signal cables is recommended to avoid noise interference.
