Stem flow is one of the subjects in the study of water balance in forest ecosystems. In hydrology, stemflow is the flow of intercepted water down the trunk or stem of a plant. Stem flow, along with through fall, are responsible for the transferral of precipitation and nutrients from the canopy to the soil. QT-Y/H stem flow collector is used to collect and analyze the stem flow.
Principle:
The system is composed of collecting units, a flow sensor and a data logger. It can continuously and automatically record the start time, end time and duration of stem flow, and also stem flow rate. The logged data can be export to excel or text file format to facilitate data processing.
Features
1. The system is suitable for all kinds of trunks. QT-Y is better for trunk diameter less than 14 cm, QT-H is for more than 14 cm.
2. It is easy to install and battery-powered, no need of external power supply.
3. The system is equipped with a sensor with high resolution of 4.13 ml
4. The data logger can record the air temperature when the stem flow is running.

A globe valve is a linear motion valve used to stop, start, and regulate the fluid flow. The globe valve disk can be removed entirely from the flow path, or it can completely close the flow path. During the opening and closing of the valve, the disc moves perpendicularly to the seat. Leakage from the globe valve seat is less as compared to the gate valve, mainly due to right angle contact between the disc and seat ring, which allows tighter seal between seats the disk.
Globe valves consist of a movable disk-type element and a stationary ring seat in a generally spherical body. The valve stem moves a globe plug relative to the valve seat. The globe plug can be at any position between fully opened and fully closed to control flow through the valve. The globe and seat construction gives the valve good flow regulation characteristics. Turbulent flow past the seat and plug, when the valve is open, results in a relatively high pressure drop, limited flow capacity, and low recovery.
Needle valves are usually used in flow-metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time, such as the idle fuel flow in a carburetor. Needle valves sometimes referred to as plunger valves. A needle valve has a relatively small orifice with a long, tapered seat, and a needle-shaped plunger on the end of a screw, which exactly fits the seat. These needle valves are an ideal option for isolating or throttling applications. The self centering, non rotating stem ensures perfect seating. The rigid design gives repetitive bubble tight shut off, easy.s.
Our range of needle valves has been designed with durability and performance in the spotlight. These needle valves are available in a variety of sizes (1/4, ½, 1/8 inch).
