Flomec G2 Flow Meter Manual Download: Sizing and Electronic Digital Display Setup
Quick Answer: The Flomec G2 manual covers turbine insert removal, K-factor entry, totalizer reset, and pulse or 4-20 mA wiring. Before you download the PDF, write down pipe size, minimum and maximum flow rate, viscosity, and required output. Silver Instruments helps teams in Southeast Asia and the Middle East match a similar flow meter when the original G2 is not available or delivery is too long.
What the Flomec G2 Manual Usually Covers
The G2 manual is used on fuel dispensing skids, small water batching lines, and light chemical dosing. Most engineers download the PDF to solve two field problems. The first is sizing a meter for a new flow range. The second is setting up the electronic display after a board swap or a lost totalizer. The manual gives K-factor ranges, wiring pinouts, and menu paths. However the PDF cannot answer process questions like back pressure, air release, or fluid compatibility beyond clean fuels and water.
Flomec G2 Sizing Data You Must Gather
Do not start with the meter model. Start with the liquid and the pipe. For diesel in a 1 inch line, a typical G2 style meter handles 20 to 120 L/min. For 50 to 250 L/min, use a 1.5 inch line. For water at ambient temperature, a 1 inch meter may cover 30 to 150 L/min. Viscosity changes everything. Diesel at 2 to 5 cP works well with a turbine insert. If viscosity is above 50 cP, a turbine meter loses accuracy. In that case an oval gear flow meter from Silver Instruments gives better repeatability for fuel oil, lube oil, or resin.
Electronic Digital Display Setup Steps
On many G2 displays, press the right arrow and the up arrow at the same time for 3 seconds to enter setup mode. The first field is usually K-factor. Enter the value from the meter tag, for example 200.0 pulses per liter. Set flow decimal to 0.1 L/min and totalizer decimal to 1.0 L. Then set the pulse output scaling. A common setting is one pulse for every 0.1 L. If the unit has 4-20 mA output, set 4 mA at 0 L/min and 20 mA at your maximum flow, such as 150 L/min. Save the settings and cycle power once. If the display still shows zero flow, check the pickup coil gap and the wiring polarity. We have seen this on customer sites many times.
Sizing Pitfalls That Manuals Do Not Fix
The manual assumes a full pipe and no air. In field conditions, a lobe pump or a gravity feed line may cause a half-filled pipe. That creates a noisy signal and totalizer drift. A paint manufacturer in Malaysia had a G2 on a solvent line. The flow rate was below the mi

FAQ: Flomec G2 Sizing and Display Setup
Where can I download the Flomec G2 manual?
Check the original manufacturer website or your local distributor portal. You can also ask us and we will send the manual file we have on record for customer support. We keep a library of common G2 documents for quick reference.
What data do I need to size a G2 style flow meter?
Provide pipe size DN, minimum and maximum flow rate, fluid type, viscosity cP, pressure bar, and temperature °C. For batching or fuel transfer, also state the required pulse per liter or 4-20 mA output.
How do I enter the K-factor on the G2 electronic display?
Enter setup mode by holding the two arrow keys for 3 seconds on most G2 displays. Go to the K-factor menu and type the value from the meter tag. Press save and exit. Always compare the display flow with a known volume before you start a batch.
Can Silver Instruments replace a Flomec G2 with a different meter?
Yes. For clean fuels and water, a turbine flow meter with a similar fitting size works well. For viscous oil, ink, or resin, we recommend an oval gear flow meter. For aggressive water or chemicals, an electromagnetic flow meter is often the better option.
What is the delivery time for a Silver Instruments meter?
Many DN15 to DN50 turbine and oval gear meters are in stock and ship within 3 to 7 days. Larger electromagnetic meters without special liners usually ship within 10 to 15 days. We ship by DHL, FedEx, or sea freight depending on your location.
