Changzhou Tianli TX-LWGY-10 Turbine Flow Meter

Changzhou Tianli TX-LWGY-10-C-05-W-S-E-N 16122036 Liquid Turbine Flow Meter

The Changzhou Tianli TX-LWGY-10-C-05-W-S-E-N (Part Number: 16122036) is an inline axial liquid turbine flow transmitter engineered for volumetric flow measurement in closed-pipe fluid systems. Built specifically for clean, low-viscosity, non-corrosive liquids, this model features a nominal diameter of DN10 with a standard threaded process connection engineered to handle working pressures up to 6.3 MPa (63 bar).

The operational mechanics rely on dynamic kinetic energy conversion: as the fluid passes through the precision-machined metering chamber, it strikes the multi-blade duplex stainless steel rotor. The angular velocity of the impeller rotates in direct linear proportion to fluid velocity. Embedded within the pickup coil assembly, an external magnetic sensor detects the passing of each rotor blade without fluid boundary penetration, generating high-frequency alternating voltage pulses. The integrated transmitter electronics condition this raw pulse train into a calibrated square-wave pulse or standardized 4–20 mA analogue transmission loop with an accuracy of ±0.5% of reading.

Frequently Asked Questions

How is the flow rate calculated from the pulse output on the TX-LWGY-10?

The flow rate is calculated using the meter’s factory-calibrated K-factor, which indicates the exact number of pulses generated per unit volume (e.g., pulses per liter). By inputting this K-factor into your PLC frequency counter or flow computer, the system calculates instantaneous volumetric flow rate and sums totalized volume over time.

Can the Changzhou Tianli TX-LWGY-10 meter be installed vertically?

Yes. The meter can be installed vertically provided the liquid flows upward through the meter body. Upward vertical flow ensures that the measuring tube remains completely flooded with fluid, eliminating pockets of entrapped air or gases that cause rotor acceleration and false reading spikes. Downward vertical flow is not recommended.

What should I do if the meter is not outputting a 4–20 mA signal?

First, verify that the external 24 VDC power supply is delivering clean voltage within the 20.4–27.6 VDC tolerance across the input terminals. Second, check the total loop impedance to verify that loop resistance does not exceed 600–900 ohms. Third, inspect the pickup coil housing for proper mechanical seating and ensure the rotor spins freely without mechanical binding from pipe particulate.

Why is an upstream strainer required for this turbine meter?

Turbine meters rely on fine tolerances between the duplex stainless steel impeller blades and the bore wall. Hard particulate matter, line rust, or pipe scale can impact the high-speed rotor, bending the blade geometry or damaging the carbide sleeve bearing surfaces. Fitting a 40- to 60-mesh strainer upstream prevents debris ingestion and preserves calibrated measurement accuracy.
