The LZM-6T is a panel-type flowmeter with a clear scale, designed for easy reading and installation. Made from acrylic capable of withstanding up to 0.6 MPa, it features a compact, lightweight form and an adjustable rate within 2-20 LPM or 4-40 SCFH. It suits panel-mounted gas monitoring in labs, workshops, or control rooms where a steady, visible readout is needed. The valve-adjustable feature helps tailor flow to process requirements.
Best for: panel-mounted gas monitoring where a clear, adjustable readout is required.
Why chosen: straightforward visual readout and adjustable control for precise process control.
Caution: ensure proper mounting hardware and connection to avoid leaks in pressurized lines.
Buying Guide
What to consider when choosing a 2-inch gas meter or related flow meter:
- outdoor, indoor, sheltered, or wet conditions determine waterproofing and enclosure needs.
- verify compatibility with water, diesel, gasoline, kerosene, or other fuels to match material and seals.
- ensure NPT threads and adapters fit your piping; confirm installation requirements.
- choose meters with ±1% accuracy and a suitable flow range for your application.
- LCD/LED displays, real-time flow, totals, and unit versatility help with reporting and logging.
- EMI protection matters in industrial environments with motors or pumps nearby.
- consider battery life, ease of replacement, and access to components without disassembly.
