Measuring
Thermal mass flow meter for compressed air and industrial gases — JAMS is the authorized CS Instruments distributor in Pakistan, offering full technical support, sales, and services.
Compressed air
Compressed air generation consumes around 10-14% of industrial electricity, with leaks causing 20-40% energy losses. Fixing leaks is the most effective way to reduce energy consumption.
Overview
Compressed air is often the most expensive and least monitored utility in a plant. Leaks, inefficient compressors, and hidden demand silently raise energy costs. The VA 500 from CS Instruments, supplied by Jams, turns airflow into actionable consumption data.
Using the calorimetric thermal mass principle, the VA 500 measures mass flow directly. Pressure or temperature swings do not force you to guess. Every cubic meter becomes visible for energy audits and ISO 50001-style programs.

In depth
Capability, accuracy, duty class, and how this product fits your process.
A robust stainless probe is built for vibration, heat, dust, and industrial electrical noise. Installation is practical: insert through a standard 1/2-inch ball valve under pressure (hot tapping) so production does not stop. An integrated depth scale centers the sensor in the pipe for a correct flow profile.
RS 485 Modbus-RTU connectivity feeds PLC, SCADA, or BMS systems for remote monitoring, historical logging, and leak detection during non-production hours. Pipe diameter and gas type configure quickly without complex programming tools.
The same thermal mass approach covers nitrogen, oxygen, argon, and other technical gases used in food packaging, pharma, and burner applications. Standardizing on one meter family simplifies spares and training across the plant.
Volume alone is deceptive: high-pressure gas packs more mass and energy than the same volume at low pressure. The VA 500 reports standard volume flow (for example Nm3/h or SCFM), the basis for fair departmental cost allocation and true energy accounting.
An integrated display shows current flow, total consumption, and velocity. Measurement spans very low leak flows up to high velocities. Dual 4-20 mA / pulse plus Modbus supports both legacy and modern systems. No moving parts means long-term stability with minimal calibration drift. Safe insertion under pressure is supported by the mounting design.

FAQ
A high-accuracy thermal mass flow meter for compressed air and industrial gases, providing real-time consumption data for energy and process work.
It is often the most expensive plant utility. Leaks and inefficiency can waste a large share of generated power if left unmeasured.
Yes. Nitrogen, oxygen, argon, natural gas, and other technical gases are common applications.
Yes. Hot-tap insertion through a standard 1/2-inch ball valve allows install under pressure.
Continuous measurement and logging reveal flow during non-production hours that usually indicates leakage.
