Oval gear fuel flow meter DN25 with pulse output

Oval gear fuel flow meter DN25 with pulse output. Two precision gears turn once for a fixed volume of fuel, so it stays accurate on viscous fuels such as heavy fuel oil (heated) and diesel.

Key features

• Size: DN25
• Accuracy: ±0.5%
• Fluids: diesel, HFO (heated), oils
• Output: pulse, 4–20 mA option

Typical uses

• Fuel to boilers, thermal oil heaters and dryers
• Generator fuel use (litres per kWh)

Connecting to Plantmargin

Wire the 4–20 mA output to a gateway analogue input, the pulse output to a pulse input, or the Modbus output to the RS485 line. Plantmargin reads flow rate and total every 10 seconds through the edge gateway, stores it for years as hourly figures, draws it against its normal band, and uses it in cost per unit, alarms and verified savings. The installer pack for your plant lists the exact register or channel to use.

Installation

• Allow a strainer upstream; straight pipe is not critical.
• The pipe must run full at the meter (for liquids): install on a rising line or a low point where possible.
• Isolation valves and a bypass let the meter be removed without stopping the line.

Before you order

• Send us the fluid, normal and maximum flow, pressure, temperature and pipe size. Flow meters are often best one size smaller than the pipe; we size it for you.
• Lead time can vary for large sizes; it is confirmed on the quotation.

Warranty and support

• Manufacturer's warranty, usually 12–24 months from delivery; the exact period is stated on your quotation.
• Supplied with the datasheet and manual; calibration or test certificate where the product has one.
• Installation, commissioning and connection to Plantmargin can be quoted with the product.
