Choosing a meter for pressure flow process measurement often comes down to a fork in the road: do you need a clamp-on ultrasonic meter for a permanent pipe, or is a simple turbine meter for a garden hose enough? The answer changes the price you pay and the kind of signal you get. These four options cover that span, from a simple hose-end meter to a full ultrasonic flowmeter.
Quick Take
If your task is process-level measurement on pipes, the ultrasonic TUF-2000B and TUF-2000M are the primary contenders. The TUF-2000M offers analog, pulse, and relay outputs, while the TUF-2000B is the other ultrasonic option in this comparison. For watering, pool filling, or RV fresh-water tank filling, the Conserve It! garden-hose turbine meter is a far simpler and cheaper match.

Decision Matrix
- Need analog and pulse outputs for a control loop? The Ultrasonic Flow Meter TUF-2000M w/ Ultrasonic Transducer TS-2 is the one with those outputs.
- Need an ultrasonic meter with a digital interface? The Wall Mounted Digital Ultrasonic Flowmeter Water Flow Meter & TM-1 TS-2 TUF-2000B supports RS485 MODBUS.
- Need a permanently clamped ultrasonic meter with data recording? The Ultrasonic Flow Meter TUF-2000B +TM-1 + TS-2 DN20~700m Fixed Clamp on Flowmeter records to an SD card.
- Need a low-cost hose-end meter for watering or filling an RV tank? The Water Flow Meter for Garden Hose for Watering or Filling RV Tank - Monitor Usage.
Product Notes
Wall Mounted Digital Ultrasonic Flowmeter Water Flow Meter & TM-1 TS-2 TUF-2000B
At $240.01, this is the higher-priced ultrasonic package and includes both a TS-2 transducer for pipes roughly 0.78 to 3.94 inches and a TM-1 transducer for pipes roughly 1.97 to 27.56 inches, along with two steel belts, a 32.81ft signal cable, and a connection terminal. It mounts on a wall or rail, uses an LCD with a built-in coin cell battery, and displays current or accumulated flow and heat when the corresponding sensor is connected. Accuracy is listed at ≤1%. Assembly is required, and the heat display works only when you add that sensor.
Ultrasonic Flow Meter TUF-2000B +TM-1 + TS-2 DN20~700m Fixed Clamp on Flowmeter
Priced at $210.70, this fixed clamp-on unit is built around the TUF-2000B host. It lists ±1% accuracy, bidirectional flow measurement, and operation that is not affected by system pressure or harsh environments. Preset results can be recorded to an SD card, but the card is not included. The ABS and steel construction is shared with the other TUF-2000B set. If you prefer a clamp-on installation to a separate display unit, this is the version to pick, and you will need to supply your own SD card.
Water Flow Meter for Garden Hose for Watering or Filling RV Tank - Monitor Usage
This Conserve It! meter is the low-cost option at $16.95. It is a turbine flow meter with a 3/4-inch port for an outdoor hose faucet, and the display reads single-use and cumulative water usage in gallons or liters. A spare black washer is included. The meter is recommended for outdoor use only, not for very high temperature water, and it needs a minimum operating pressure of 7.3 psi. For watering, pool filling, or RV fresh-water tank filling, this meter gives you a direct readout without the setup of an ultrasonic system.
Ultrasonic Flow Meter TUF-2000M w/ Ultrasonic Transducer TS-2
At $150.00, the TUF-2000M is the least expensive ultrasonic host in this lineup. It is aimed at municipal water, wastewater treatment, and industrial flow measurement, and it provides a 4-20mA output, an OCT pulse output, a relay output, and three 4-20mA inputs. The product name names only the TS-2 transducer, while the TUF-2000B bundles name both TS-2 and TM-1 transducers, so pipe coverage is a point to weigh before choosing. This is a focused ultrasonic host for applications that need analog and pulse signals.
