GPI G2S15NQ9GMB Turbine Flow Meter: Compact Digital Liquid Measurement
Quick Answer: The GPI G2S15NQ9GMB is a modular turbine flow meter with a built-in digital display. It measures clean, low-viscosity liquids from 3 to 30 L/min with ±1% accuracy. Pulse and 4-20 mA outputs make it easy to feed data into PLCs, batch controllers, or local indicators. Silver Instruments stocks these meters and ships to Southeast Asia, Oceania, Africa, and the Middle East.
What Is the G2S15NQ9GMB Turbine Meter
This model belongs to the GPI G2 series. The digital module sits directly on the meter body. You get a local readout of flow rate and total volume without wiring a separate display. The body is machined from anodized aluminum with a 15 mm turbine chamber. End connections are 1/2 inch NPT female. The meter handles liquid temperatures up to 60 °C and pressures to 20 bar. Because the bearings are ceramic and the shaft is tungsten carbide, the rotor spins freely even after months of continuous duty.
Key Technical Specifications
Flow range is 0.8 to 8.0 US GPM (3 to 30 L/min). Most customers run it between 5 and 20 L/min for stable readings. Accuracy is ±1% of reading across the linear range. Repeatability stays within ±0.2%. The digital module requires 12 to 35 VDC and draws less than 30 mA. Output options include an open-collector pulse (scalable via K-factor) and an active 4-20 mA loop. The local LCD flips between rate and total. A resettable batch total and a non-resettable cumulative total are standard. Wetted materials are aluminum, 316 stainless steel, ceramic, and Viton seals. The meter comes with an IP65 rating, so light washdown is fine.
Industries and Typical Installations
We see these meters in water purification skids, diesel fuel monitoring, chemical dispensing, and cooling tower make-up lines. A paint manufacturer in Vietnam uses eight G2S15 units on solvent and resin lines. They told us the modular digital display cut their wiring time by half compared to separate transmitter loops. A water treatment contractor in Kenya installed twelve units in a solar-powered rural distribution network. The low current draw let them run the meters from battery-backed PLC panels without voltage drop issues. In Australia, beverage companies place them after RO systems to track permeate flow into blending tanks.
How to Order and Get a Quote from Silver Inst
When you request a quotation, include the liquid type, expected flow range, pipe size, operating pressure, and temperature. That helps us confirm the seal material and K-factor settings. We also ask about your output preference: pulse only, 4-20 mA only, or both. If you need ATEX Zone 1 approval, let us know early. We will suggest an alternative model because the G2S15NQ9GMB is not certified for hazardous areas.

FAQ
Q: What liquids work with the G2S15NQ9GMB?
A: The meter is designed for clean, low-viscosity fluids. Water, diesel, kerosene, glycol, and weak acids are common. Avoid liquids with solids, fibers, or viscosity above 5 cP. If you need to measure high-viscosity oil, see our oval gear flow meter range.
Q: How do I connect the pulse output to a PLC?
A: The open-collector pulse needs a pull-up resistor. Most engineers use a 2.2 k? resistor to the PLCs 24 VDC input. The K-factor is stamped on the label. One pulse equals 0.46 mL for this model. Scale inside your PLC logic to get the required engineering unit.
Q: Does this meter show total volume in liters or gallons?
A: The digital display can be toggled between liters and US gallons via a small button under the front panel. The factory setting is liters. Total values are non-volatile, so you keep the data after a power cycle.
Q: Can I install the meter outdoors without a cover?
A: IP65 handles rain and splashes, but direct sunlight for months will yellow the LCD and degrade the plastic housing. Use a simple sun shield. In cold regions, keep the line insulated so the liquid does not freeze inside the turbine chamber.
Q: What is the lead time for the G2S15NQ9GMB?
A: Silver Instruments keeps these in stock in Nanjing. Small quantities up to 10 pieces ship within 3 working days. Larger orders require 2 to 3 weeks if we need to pre-configure K-factors or special seals. We will give you a firm delivery date when you email your required quantity.
